The full 20-day circuit is one of the most complete Bhutan travel experiences available, combining genuine wilderness trekking with authentic cultural access in a format that cannot be replicated on shorter packages.Laya Gasa Trek Bhutan – 20 Days Route

The Laya Gasa Trek route begins in Paro, entering the trekking corridor at Sharna (2,870 m) on Day 2 via a short acclimatization hike that also serves as a gear and fitness check.

The trail follows the Paro Chhu river valley upstream through mixed broadleaf and blue pine forest before climbing steeply to Thangthangka (3,630 m) and then to Jangothang (4,090 m), the base camp below Mount Jomolhari. 

This section shares the first four days with the classic Jomolhari Trek, and the dramatic approach to Jangothang, where the full south face of Jomolhari dominates the skyline, is consistently rated among the most visually powerful camp arrivals on any Himalayan trail.

After a rest day at Jangothang with the option of a glacier hike to 5,200 m for fit trekkers with no AMS symptoms and guide approval, the route crosses into the Lingshi valley via the Nyele La approach (4,870 m), descending to Lingshi Dzong (4,010 m), a remote fortress at the foot of the pass.

From Lingshi, the route diverges from the Jomolhari circuit and presses north through Chebisa (3,880 m), Shomuthang (4,220 m), Robluthang (4,160 m), and Limithang (4,140 m) before descending into Laya (3,840 m) on Day 11.

This central section of the Laya Gasa Trek is the most remote, passing through yak herder settlements, crossing the Gobula Pass (4,320 m) and Jarila Pass (4,600 m), and offering sustained views of Gangchhenta (Great Tiger Mountain, 6,678 m) and the Masang Gang massif.

Wildlife sightings are most frequent in this corridor. After a rest day at Laya, the descent route to Gasa follows the Mo Chhu (Mother River) valley south through Koina (3,050 m) and Gasa village (2,770 m), visiting the thermal hot springs before continuing through Geon Damji (2,430 m) and Tashithang (1,840 m), where road access resumes.

The final trekking days drop through dense fir and juniper forest, transitioning from alpine wilderness to the subtropical Punakha valley floor at 1,310 m, one of the most dramatic altitude descents on any Bhutan trekking itinerary.

Post-trek, the 20-day package incorporates a guided tour of Punakha Dzong and the Khamsum Yulley Namgyel Chorten before the drive to Thimphu for cultural sightseeing and onward to Paro for the iconic Tiger’s Nest hike.

These final stages are not an afterthought; Punakha Dzong, standing at the confluence of the Pho Chhu (father river) and Mo Chhu (mother river), is considered the most beautiful dzong in Bhutan and was the winter capital of the kingdom for over three centuries. 

Who Can Do the Laya Gasa Trek in Bhutan – 20 Days?

The Laya Gasa Trek is designed for trekkers with solid physical fitness, prior multi-day hiking experience at altitude, and a realistic appreciation of the effort involved in sustained high-altitude camping over two weeks. This is not a beginner trek.

The route covers approximately 166 km of mountain terrain over 14 active trekking days, with several days exceeding 17–22 km and cumulative elevation gains of 700–900 m. Campsites sit between 3,050 m and 4,220 m for the majority of the route, and the physiological demands of sleeping and exercising above 3,500 m should not be underestimated.

This challenge suits trekkers who have completed multi-day trails such as the Annapurna Circuit, Everest Base Camp, or a comparable Himalayan route.

No technical climbing experience is required for the standard 20-day itinerary. All passes are trail passes, not ice or rock routes.

However, the combination of distance, altitude, remote terrain, and variable weather from late spring onwards requires specific preparation. Trekkers should complete at least 12–16 weeks of aerobic conditioning before departure, including regular hill walking with a loaded pack. 

Participants with well-managed cardiovascular health, normal blood pressure, and no history of high-altitude pulmonary or cerebral edema can attempt this trek safely when supported by a professional guide.

Those over 50 or with any pre-existing health conditions should obtain medical clearance before booking. Our team at Aura Trails assesses readiness during the booking consultation and can recommend pre-trek training frameworks if requested.

Notable Mountains Along the Laya Gasa Trek

Mount Jomolhari (7,326 m)

Mount Jomolhari, translating from Tibetan as ‘Mountain of the Goddess,’ rises to 7,326 m on the Bhutan-Tibet border above the Paro valley and is considered one of the most sacred peaks in the Himalayan Buddhist tradition.

The mountain is revered as the residence of the goddess Jomo, protector deity of the region, and its name appears throughout religious texts connected to both the Drukpa Kagyu and Nyingma traditions of Vajrayana Buddhism. 

Jomolhari’s south face dominates the skyline above Jangothang Base Camp (4,090 m) and is visible from the campsite with extraordinary clarity on clear mornings.

The first ascent was made by Frederick Spencer Chapman and Sherpa Pasang Dawa Lama in May 1937; subsequent attempts on the mountain have been severely restricted by the Bhutanese government out of respect for its sacred status.

Trekkers on the Laya Gasa route spend two nights directly below this peak, and the unobstructed early-morning views of the summit pyramid from Jangothang are consistently described as the most visually powerful moment of the entire journey.

Gangchhenta / Great Tiger Mountain (6,678 m)

Gangchhenta, known in Bhutanese as ‘Great Tiger Mountain,’ stands at 6,678 m in the northern Bhutan Himalayas and forms the dominant peak visible from the middle section of the Laya Gasa Trek between Lingshi and Laya.

The mountain sits within Jigme Dorji National Park and has never been summited; like several of Bhutan’s high peaks, it remains off-limits to climbing in honor of its spiritual significance. 

Gangchhenta is particularly prominent above the Shomuthang and Robluthang campsites (Days 8–9), where the peak’s western ridgeline defines the northern horizon across the high plateau.

The accompanying Masang Gang massif (7,194 m) is also visible from Laya village, forming a dramatic northern backdrop to the settlement’s terraced hillside.

Best Season for Laya Gasa Trek Bhutan – 20 Days

Spring, running from mid-March through May, is the primary recommended window for the Laya Gasa Trek. March and April bring gradually clearing skies after winter, stable daytime temperatures at altitude (0–8°C at camp, rising to 12–18°C during active trekking hours), and the spectacular bloom of rhododendrons across the forested sections between 2,800 m and 3,800 m. 

The Himalayan Blue Poppy, Bhutan’s national flower, begins to emerge in meadows above 3,500 m in late April and peaks through May. Mountain visibility is generally excellent in March and April before the pre-monsoon haze builds in late May.

Wildlife is more active during spring: Takin calves appear in the Chebisa and Tsharijathang corridors, and bird activity peaks along the entire route. 

Late May carries an increasing risk of afternoon rain and early monsoon moisture, particularly in the lower valley sections.

Many trekkers favor autumn, from September through mid-November, for its exceptional post-monsoon mountain clarity, making it the second major trekking window.

September and October deliver the clearest high-altitude skies of the year; photographers can capture Jomolhari and Gangchhenta against intensely blue horizons with no atmospheric haze. 

Deciduous forest in the lower and mid-altitude sections turns gold and red through October, adding visual richness to the descent from Laya toward Gasa. Temperatures are slightly colder than in spring at equivalent altitudes; at Shomuthang and Laya, night temperatures can fall to between -8°C and -12°C in October.

The trail is dry and firm through this period. November becomes increasingly cold above 4,000 m and is not recommended for inexperienced groups. Winter (December–February) and the full monsoon period (June–August) are not suitable for this route.

Weather, Temperature & Climate Information

The Laya Gasa Trek corridor spans elevations from 1,310 m (Punakha) to 4,220 m (Shomuthang campsite), and weather conditions vary substantially across this range. In spring (March–May), daytime temperatures at Paro (2,250 m) range from 10–18°C; at Jangothang (4,090 m) and Shomuthang (4,220 m), daytime highs rarely exceed 8–10°C and can drop to -4°C overnight. 

Wind is the primary weather challenge above 4,000 m, particularly at the high campsites and on-pass crossings; wind speeds of 40–60 km/h are not unusual at the Nyele La approach and Jarila Pass.

In autumn, the same altitude bands run 3–5°C colder than spring equivalents; overnight temperatures at Laya (3,840 m) in October commonly reach -6°C to -10°C. Precipitation is rare in the trekking seasons: March–April brings occasional light snow above 4,000 m, while September–October is statistically the driest period of the year.

All trekkers should carry full waterproof layers, an insulated down or synthetic jacket rated to a minimum of -10°C, and a four-season sleeping bag. Each morning, guides give weather briefings based on current mountain conditions.

Required Permits

All trekking in Bhutan is regulated by the Tourism Council of Bhutan (TCB), and independent trekking is strictly prohibited.

Every permit is arranged and submitted by Aura Trails before the trekker arrives in Paro; no permits are collected or paid separately on arrival. The following permits are required for the Laya Gasa 20-Day itinerary:

• Bhutan Tourist Visa: Required by all nationalities except Indian, Bangladeshi, and Maldivian nationals. Applied for through TCB via the licensed operator; the processing fee is USD 40 per person.
• Bhutan Tourist Permit (Visitor Permit): The primary entry authorization document, collected at Paro Airport and carried throughout the trip. Issued by TCB.
• Trekking Permit: Required for all multi-day trekking routes. Applied for by the licensed operator and verified at the trailhead before Day 2.
• Jigme Dorji National Park Entry Permit: Required for trekking within the park boundaries, which encompasses most of the Laya Gasa Trek route from Sharna onward. Park entry fee is included in the package cost.
• Restricted Area Permit (Laya): Laya is classified as a restricted zone under Bhutanese government regulation. A special restricted area permit is required and must be submitted in advance. The permit is checked at the Bhutan Army camp at Laya on Day 11 and again at the army post above Gasa village on Day 14. This permit is arranged entirely by our team.
• Sustainable Development Fee (SDF): USD 100 per person per night for international tourists (excluding Indian, Bangladeshi, and Maldivian nationals who pay USD 15 per person per night). Collected by the operator and remitted to the government. Children aged 6–12 receive a 50% discount; children under 6 are exempt.

Difficulty

The Laya Gasa Trek is rated strenuous to difficult and sits at the harder end of Bhutan’s multi-day trekking spectrum. The difficulty derives from three compounding factors: sustained duration (14 consecutive trekking days), consistent high altitude (9 of 14 trekking days above 3,800 m), and daily walking distances that regularly exceed 17–22 km with significant elevation changes. 

The trail surface ranges from well-maintained forest paths in the lower sections to rocky glacial moraine, exposed ridgeline traverses, and boggy high-altitude meadow in the central section between Lingshi and Laya.

There are no technical climbing sections; all passes are walk-up trail passes requiring only hiking fitness. The most demanding single day is Jangothang to Lingshi (Day 6), which involves the approach to Nyele La (4,870 m) and covers 17 km in 6–7 hours with an ascent of approximately 880 m.

Trekkers should begin structured physical preparation at least 12 weeks before departure. A recommended training framework includes four to five cardiovascular sessions per week (running, cycling, stair climbing, or swimming); two to three loaded day hikes per week over progressively longer distances and elevation gains; core and leg strength training twice weekly; and at least two overnight backpacking trips with a pack of 8–10 kg in the eight weeks before departure. 

No specific technical skills are required beyond standard mountain awareness. Trekkers should be comfortable reading trail conditions, adjusting pace for altitude, and communicating physical symptoms clearly to guides.

Previous experience on multi-day Himalayan treks at altitudes above 3,500 m is strongly recommended but can be substituted with comparable high-altitude fitness work under the guidance of our pre-trek preparation team.

Physical and Mental Preparation

Preparing for a 20-day high-altitude trek in Bhutan requires a structured approach covering both physical conditioning and mental readiness.

The physical demands of the Laya Gasa Trek are not just cardiovascular; muscular endurance in the legs and core, the ability to maintain focus and decision-making under fatigue, and tolerance for consecutive days in remote terrain without modern conveniences are all tested.

A progressive 12–16 week preparation plan should address all of these dimensions.

• Begin cardiovascular training 12–16 weeks before departure: target 45–60 minutes of moderate-to-vigorous aerobic exercise five days per week
• Include at least two loaded hill or mountain hikes per week, progressively increasing pack weight from 6 kg to 10 kg over the preparation period
• Complete at least two overnight trekking trips in the final eight weeks to simulate consecutive trekking days
• Train specifically for descent: eccentric leg exercises, downhill hiking, and lunges reduce DOMS and knee strain on long descent days
• Maintain consistent hydration habits during training: aim for 2.5–3 litres of water daily and practice drinking regularly on the move
• Consult a physician regarding acetazolamide (Diamox) prophylaxis for altitude sickness; obtain prescription before departure if recommended
• Build mental resilience: practise tent sleeping in variable weather conditions, cold exposure management, and sustained activity without digital distraction
• Review the gear list (Section 19) thoroughly and conduct at least one full gear test hike in all major items before departure
• Obtain comprehensive travel insurance covering high-altitude trekking and helicopter evacuation before finalising the booking

Accommodation & Meals

We provide pre- and post-trek accommodation in Paro, Punakha, and Thimphu in 3-star or equivalent standard hotels, selected for location, cleanliness, and service quality.

In Paro, the opening and closing nights are spent in valley-view hotels within easy walking distance of the town center; in Thimphu and Punakha, central properties with en-suite rooms, hot water, and Wi-Fi are standard.

Hotel breakfasts are included in the package; dinners on city nights are either included (as specified) or at the trekker’s choice from local restaurants, which our guide can recommend.

Accommodation on the trek (Days 2–16) is exclusively in tented camps managed by our crew. All tents are maintained to expedition standards: two-person mountain tents with waterproof fly sheets, insulated sleeping mats, and wind-resistant pegging systems.

Separate dining tents with folding tables and chairs are erected at each campsite. A separate cook’s kitchen tent and toilet tent are standard at every camp.

Trekkers are responsible for their sleeping bags and personal items; sleeping bags are not provided but can be rented on request (a four-season rated bag is strongly recommended: minimum -15°C comfort rating).

All meals on the trek are prepared by our trained cook and kitchen staff from fresh provisions carried by pack animals. Breakfasts include porridge, eggs, toast, tea, and coffee.

Packed lunches comprise sandwiches, energy bars, dried fruit, cheese, and seasonal items. Hot dinners are three-course meals featuring rice, lentils (dal), seasonal vegetables, meat dishes (chicken or yak beef on most days), soup, and dessert. 

Dietary requirements including vegetarian, vegan, and gluten-intolerant diets are fully accommodated with advance notice at the time of booking. Clean drinking water is provided at all campsites; water purification tablets are also carried by all guides.

Trekkers are strongly advised to carry personal water bottles or hydration systems with a minimum 2-liter capacity. At city hotels, breakfast is the only included meal. Thimphu, Punakha, and Paro all have restaurants serving both Bhutanese cuisine and international food; our guides can make recommendations and, where requested, facilitate group dinners at local restaurants that showcase authentic Bhutanese dishes such as ema datshi (chilli and cheese), phaksha paa (pork with red chili), and red rice with fresh vegetables. Bhutan’s national food culture, centered on chili as both vegetable and spice, is a memorable part of the overall journey.

Transportation

All surface transportation within Bhutan for the 20-day package is provided in private, air-conditioned Toyota Land Cruisers or equivalent 4WD vehicles with experienced government-registered drivers. Airport pickup on arrival day and drop on departure day are included. All inter-city drives for sightseeing days (Punakha to Thimphu, Thimphu to Paro) and the trek trailhead transfer (Paro to Sharna via Drukgyel Dzong) are included. 

The key vehicular section within the trek is the Day 16 drive from Tashithang to Punakha along the Mo Chhu valley road (approximately 1 hour). International flights to and from Paro are not included in the package. Paro is served exclusively by Bhutan’s two national airlines Druk Air and Bhutan Airlines, with connections through Bangkok, Delhi, Kolkata, Kathmandu, Mumbai, and Singapore. 

Our team can assist with flight booking on request; Paro flight inventory is limited and early booking (3–6 months ahead) is strongly recommended for spring and autumn departures.

Travel Insurance

Comprehensive travel insurance is mandatory for all participants on the Laya Gasa Trek Bhutan 20-Day package and must be arranged before the booking is confirmed. The policy must include emergency medical treatment covering a minimum of USD 100,000; helicopter medical evacuation coverage specifically for high-altitude trekking above 4,000 m; trip cancellation and curtailment (recommended minimum USD 5,000); baggage and personal effects cover; and personal liability. 

Standard travel insurance policies often exclude high-altitude trekking above 3,000 m or 4,000 m; trekkers must verify that their policy explicitly covers activities at the altitudes encountered on this itinerary. Providers with proven Himalayan trekking coverage include World Nomads, Battleface, Safety Wing (Adventure plan), IMG Global, and Ripcord Rescue Travel; however, we recommend independent verification of specific policy terms before purchase. 

Proof of valid insurance must be submitted to Aura Trails before departure documents are released. In the event of a medical emergency requiring helicopter evacuation, our guides coordinate with the nearest Bhutanese medical facility and the helicopter operator directly; insurance documentation must be accessible to the guide throughout the trek.

Altitude Sickness & Prevention

Altitude sickness (Acute Mountain Sickness, AMS) is the most significant health risk on the Laya Gasa Trek and requires active management by every participant. AMS occurs when the body cannot adapt quickly enough to the reduced atmospheric oxygen pressure at altitude, typically above 2,500 m. 

On this itinerary, trekkers are at meaningful altitude risk from Day 3 onward (Thangthangka, 3,630 m) and remain above 3,800 m for nine of the fourteen trekking days. The two acclimatization rest days at Jangothang (4,090 m) and Laya (3,840 m) are medically significant and must not be skipped. Guides are trained in AMS recognition and carry emergency medication; however, individual awareness of symptoms is essential for safe trekking.

Symptoms of AMS (mild to moderate)

• Persistent headache not relieved by standard analgesics
• Fatigue and weakness disproportionate to exertion
• Loss of appetite, nausea, or vomiting
• Disturbed sleep or insomnia
• Dizziness and mild disorientation

Symptoms requiring immediate descent (HAPE / HACE)

• Severe headache with confusion, disorientation, or loss of coordination (HACE – High Altitude Cerebral Oedema)
• Breathlessness at rest, persistent cough, or frothy/pink sputum (HAPE – High Altitude Pulmonary Oedema)
• Inability to walk in a straight line
• Extreme fatigue preventing forward movement

Prevention protocols

• Follow the ‘climb high, sleep low’ principle: the daily net altitude gain at campsites is managed within 300–500 m above 3,000 m
• Maintain fluid intake of 3–4 litres per day throughout the trek
• Avoid alcohol at altitude; limit caffeine
• Eat regular carbohydrate-rich meals to support metabolism under low-oxygen conditions
• Report any symptoms immediately to your guide; never assume symptoms will resolve without action
• If symptoms do not improve with one night of rest at the same altitude, the default response is descent; no schedule pressure justifies continuing with active AMS
• Acetazolamide (Diamox) prophylaxis: discuss with your physician before departure; standard preventive dose is 125–250 mg twice daily beginning 24 hours before ascent to altitude

Emergency and Medical Evacuation Services

Bhutan has an established emergency medical evacuation infrastructure that our team activates in the event of a serious medical incident on a trek. Our senior guides carry satellite communication devices and maintain direct contact with Aura Trails’ Paro operations center throughout the trek. In the event of AMS progression to HACE or HAPE, the immediate response is assisted rapid descent; our support crew carries Gamow bags (portable hyperbaric chambers) and supplemental oxygen on request. 

For trauma injuries, acute illness, or any condition requiring hospitalization, helicopter evacuation is available through Bhutan Government helicopter services operating from Punakha and Paro. Evacuation is coordinated through our operations center and requires the trekker’s travel insurance documentation; this procedure underlines the non-negotiable requirement for comprehensive trekking insurance before departure. 

The nearest hospital with surgical capacity to the trekking route is Punakha District Hospital; Thimphu National Referral Hospital (Jigme Dorji Wangchuck National Referral Hospital) provides the highest level of in-country care. For cases requiring international medical facilities, evacuation is to Kolkata or Bangkok depending on the treating physician’s recommendation. 

Guide and Porter

All Bhutan trekking packages must be accompanied by a government-certified guide; independent trekking is not permitted by law. Aura Trails assigns a senior English-speaking lead guide with a minimum of five years’ specific experience on the Laya Gasa corridor to each group. 

In larger groups, assistant guides accompany the rear and midsection of the trekking party to maintain pace management and monitor trekkers individually. Our lead guides hold first aid certification with wilderness protocols, carry emergency medication kits, and receive regular refresher training on AMS recognition and management. 

The support crew includes a trained cook, kitchen assistant, and horsemen who manage pack animal logistics. The horse handlers and pack animals carry all group camping equipment, kitchen provisions, and surplus communal gear; individual trekkers carry their own daypack with daily essentials. 

Personal porters for trekkers’ personal duffel bags are available at an additional cost and can be arranged at booking; the standard duffel bag weight limit for pack animal transport is 15 kg per trekker.

Important Notes

• Bhutan does not permit independent trekking; every trekker must be accompanied by a TCB-licensed agency’s certified guide throughout the itinerary
• The Laya Restricted Area Permit requires advance submission to TCB; applications through Aura Trails should be initiated a minimum of 4–6 weeks before departure to guarantee processing
• The SDF rate of USD 100 per person per night is fixed until August 2027 under the current TCB framework; verify current rates at the time of booking
• The itinerary is designed with two mandatory rest days at Jangothang (Day 5) and Laya (Day 12) that cannot be shortened; doing so creates unacceptable altitude risk for subsequent days above 4,000 m
• Pack animals (horses or mules) are used for group equipment; there are no wheeled vehicles accessible beyond the Sharna trailhead until Tashithang on Day 16; the trek is fully self-sufficient once underway
• Mobile network coverage is absent throughout the trekking section (Days 2–16); satellite communication devices are carried by our guides and are the only reliable communication method in the backcountry
• All waste generated on trek is carried out of the national park; no litter is left at campsites or on trail; trekkers should carry personal waste bags and follow Leave No Trace principles
• Photography inside temples, dzongs, and religious sites is subject to restrictions; follow your guide’s direction and respect signage; drone photography in Bhutan requires a separate government permit not included in the standard package
• Currency: the Bhutanese Ngultrum (BTN) is pegged 1:1 to the Indian Rupee; USD and major currencies are exchangeable at Paro Airport and banks in Thimphu and Paro; no currency exchange is available on the trekking section
• The Bhutan Government bans plastic bags; trekkers should bring reusable bags and eco-friendly toiletry containers; biodegradable soap and shampoo are mandatory on all national park sections of the route
• Altitude medication (Diamox) is not available over the counter in Bhutan; trekkers who have received a physician’s recommendation should bring an adequate supply from their home country
• Booking cancellations made more than 60 days before departure incur a processing fee; cancellations within 30–60 days forfeit 50% of the package cost; cancellations within 30 days forfeit the full cost detailed cancellation terms are provided in the booking agreement

Frequently Asked Questions

1. What is the total cost of the Laya Gasa Trek Bhutan – 20-day combined package?

Package pricing varies based on group size, travel season, hotel category selection, and optional add-ons such as personal porters. The SDF alone accounts for USD 2,000 per person for a 20-night stay at the current government rate of USD 100 per person per night. Contact Aura Trails for a current, itemized quotation with a transparent cost breakdown. Group discounts are available for parties of four or more.

2. What services are included and excluded in the package price?

Full inclusions are listed in Section 8 (Cost Includes) and exclusions in Section 9 (Cost Excludes). In summary: the package covers all permits, SDF, guide and crew, camping equipment, all meals, hotel accommodation in Paro/Punakha/Thimphu, in-country transportation, and guided sightseeing. International flights, travel insurance, personal gear, personal porter hire, and gratuities are not included.

3. How difficult is the Laya Gasa Trek in Bhutan – 20 Days, and do I need prior experience?

The trek is rated as strenuous to difficult. Prior high-altitude trekking experience above 3,500 m is strongly recommended. Trekkers who have completed multi-day Himalayan routes (Everest Base Camp, Annapurna Circuit, or comparable) are well-positioned for this trek. No technical climbing skill is required, but sustained physical conditioning over 12–16 weeks before departure is essential.

4. What is the best season to do the Laya Gasa Trek in Bhutan – 20 Days?

Spring (mid-March to May) and Autumn (September to mid-November) are both excellent. Spring offers rhododendron blooms and the Himalayan Blue Poppy; autumn delivers the clearest mountain visibility of the year. March–April and October are the optimal months within each window.

5. How cold does it get during the trek, especially in spring or autumn?

Night temperatures at high campsites (Jangothang, Shomuthang, and Laya) range from -4°C to -12°C depending on month and season. Daytime trekking temperatures are 6–15°C at altitude. A four-season sleeping bag rated to -15°C comfort and a down jacket rated to -10°C are the minimum gear requirements for staying warm.

6. What type of accommodation is provided during trekking and at hotels?

Hotel stays in Paro, Punakha, and Thimphu are 3-star or equivalent standard with en-suite rooms and hot water. All trekking nights use our expedition-standard two-person mountain tents with insulated sleeping mats. A dining tent and toilet tent are erected at every campsite.

7. Do I need travel insurance? What should it cover?

Travel insurance is mandatory and must be confirmed before booking is finalized. The policy must cover: emergency medical treatment (minimum USD 100,000), helicopter evacuation from high-altitude trekking terrain (above 4,000 m), trip cancellation, and baggage. Standard policies that exclude activities above 3,000–4,000 m are not sufficient; confirm altitude coverage with your insurer.

8. How fit do I need to be for this 20-day trek?

You should be able to walk 15–22 km per day with a 6–10 kg daypack over 6–9 hours of continuous movement, at altitudes between 3,000 m and 4,220 m, for 14 consecutive days. You need to have cardiovascular fitness equivalent to regular running (30+ km/week) or hiking with a loaded pack (10+ km/week) as the baseline requirement. Start structured training at least 12 weeks before departure.

9. What permits are required, and are they arranged by your company?

Yes, all permits are arranged entirely by Aura Trails. Required permits include the Bhutan Tourist Visa, Tourist Permit, Trekking Permit, Jigme Dorji National Park Entry Permit, and Restricted Area Permit for Laya. All are included in the package and managed through our TCB-licensed operations process. Applications begin upon receipt of your booking confirmation and passport details.

10. How many acclimatization days are included?

Two full acclimatization rest days are included: Day 5 at Jangothang (4,090 m) and Day 12 at Laya (3,840 m). Both are mandatory components of the itinerary and cannot be removed. Optional exploratory day hikes on rest days support physiological adaptation through ‘climb high, sleep low’ protocols.

11. What is the group size, and can I join a group or book a private trip?

We accommodate groups from a minimum of 2 to a maximum of 10 trekkers per departure. Private departures can be scheduled on most dates within the trekking season. Small shared-group departures are available at a lower per-person cost. Contact us to check current shared group departures.

12. What kind of meals are provided during the trek?

All meals on trekking days are included. Breakfasts are hot and cooked: porridge, eggs, toast, tea, and coffee. Packed lunches are prepared each morning: sandwiches, energy bars, fruit, and cheese. Our crew cooks hot three-course dinners each evening. We accommodate vegetarian, vegan, and gluten-free diets with advance notice.

13. Can beginners attempt the Laya Gasa Trek in Bhutan for 20 days?

This trek is not recommended for beginners with no prior multi-day trekking or high-altitude experience. Trekkers who have only done short day hikes or low-altitude trails should build up to this route over one to two seasons, with progressively more demanding treks, before attempting the Laya Gasa 20-Day itinerary. Our team can recommend preparatory treks in Bhutan or Nepal for those building toward this objective.

14. What equipment do I need to bring from home?

Key personal items that must be brought from home include broken-in waterproof trekking boots, a four-season sleeping bag (rated -15°C), a down jacket, waterproof outer layers, glacier sunglasses, a daypack, a duffel bag, and any prescription medications. See Section 19 for the full gear checklist. Our team provides a detailed pre-departure gear list upon booking confirmation.
