Overview
The Laya–Gasa Trek is one of Bhutan’s most scenic and rewarding high-altitude treks, offering an unforgettable journey through some of the country’s most remote and unspoiled Himalayan landscapes. This 14-day adventure covering approximately 217 km begins at Drukgyel in Paro and winds through alpine meadows, dramatic mountain passes, dense forests, and isolated villages before concluding in Gasa.
For the first five days, the route follows the iconic Jomolhari Trek, passing through Jigme Dorji National Park with breathtaking views of Mount Jomolhari, Jichu Drake, and Tsherimgang. The trail then diverges toward Chebisa and Laya, introducing trekkers to the unique culture of the Layap people, known for their distinctive traditions and dress.
Wildlife sightings along the trail may include blue sheep, takin (Bhutan’s national animal), marmots, and Himalayan birds. A major highlight of the trek is a relaxing soak at the Gasa Hot Springs, a perfect reward after days of challenging mountain trekking.
Due to high elevations, long walking days, and steep ascents and descents, the Laya–Gasa Trek is considered physically demanding and best suited for experienced trekkers. The ideal trekking seasons are April to June and mid-September to mid-November.
Trek Itinerary
The trek begins at Gunitsawa Village, the roadhead near Drukgyel Dzong. After completing permit formalities at the army checkpoint, you follow the Paro Chhu River on a gentle trail through forested terrain. The short hike allows time to settle into the rhythm of trekking before reaching the Sharna Zampa campsite, set beside the river and surrounded by pristine wilderness.
Today is a long but rewarding walk through the beautiful Paro Chhu Valley, with gradual ascents and descents through pine forests and open meadows. The valley narrows as altitude increases, and if weather conditions are clear, you may catch your first views of Mount Jomolhari. Camp overnight at Thangthangkha, a wide meadow beneath towering mountain walls.
The trail continues upstream through alpine terrain dotted with yak herders’ settlements. Snow-capped peaks dominate the horizon as you pass through villages such as Soe, Takethang, and Dangochang. By afternoon, arrive at Jangothang, widely regarded as one of the most beautiful campsites in the Himalayas, offering stunning views of Mount Jomolhari.
A full rest and acclimatisation day at Jangothang. Optional hikes lead to surrounding ridges and glacial lakes with spectacular views of Jomolhari and Jichu Drake. This area is also home to blue sheep, often spotted grazing on the high slopes. The day allows your body to adjust to altitude while enjoying the dramatic Himalayan scenery.
After leaving Jangothang, the trail climbs steadily to Nyilila Pass (4,870m), offering panoramic views of Jomolhari, Jichu Drake, and Tsherimgang. Descend gradually into the broad Lingshi Valley, where yak herders’ camps dot the landscape. On clear days, enjoy views of Lingshi Dzong, perched dramatically on a ridge above the valley.
A relatively shorter and gentler day. You may take an optional detour to visit Lingshi Dzong, known for its remote and spiritual atmosphere. Continue through the villages of Lingshi and Goyul before arriving at Chebisa, a picturesque village famous for its crystal-clear waterfall and traditional stone houses.
The trail ascends gradually behind Chebisa through open pastures toward Gobu La Pass. Along the way, you may encounter yak herders and large herds of blue sheep. After crossing the pass, descend into a wide U-shaped valley before climbing again to reach Shomuthang campsite, set beside a tributary of the Nochu River.
Climb steadily toward Jhari La Pass, passing alpine flowers and enjoying views of Gangchhenta (Great Tiger Mountain). This region is part of a protected takin sanctuary, and sightings of Bhutan’s national animal are common in summer months. The campsite at Robluthang lies in a high, rocky meadow surrounded by dramatic peaks.
A challenging but spectacular day as you cross Sinche La Pass (5,005m), the highest point of the trek. From the pass, descend past glaciers, moraines, and glacial lakes into the remote valley of Limithang, with commanding views of Gangchhenta towering above the campsite.
Descend gradually along a narrow river valley, entering forested terrain as you approach Laya Village, one of the highest permanent settlements in Bhutan. Explore the village and observe the unique culture and traditional dress of the Layap people. The campsite is located near the village school.
Follow the rugged Mo Chhu River Valley, crossing streams and waterfalls while navigating a series of ascents and descents. The trail offers dramatic river views before descending to the riverside campsite at Koina.
The final trekking day involves crossing Bari La Pass (3,740m) before a long descent to Gasa Village, home to a distinctive hilltop Dzong. From here, you may continue to the famous Gasa Hot Springs to soak in the therapeutic mineral waters—an ideal way to end this demanding yet rewarding trek.
