Gasa, Bhutan
Hot Springs of the Himalayas · Gateway to Laya
The Kingdom's Remote & Sacred North
Gasa is Bhutan's northernmost and most remote dzongkhag (district), bordering Tibet. It is a land of extraordinary natural beauty — glacial rivers, ancient forests, high alpine pastures, and Himalayan peaks rising above 7,000m. For most of Bhutan's history, Gasa was almost entirely inaccessible from the south, connected to Punakha only by a difficult trail through the Mo Chhu river gorge.
Today, a road links Punakha to Gasa town, though significant sections remain unpaved and the journey can take 3–4 hours. The relative difficulty of access has preserved Gasa in a state of remarkable authenticity. The population includes the Layap people — semi-nomadic yak herders who inhabit the high-altitude village of Laya — who maintain one of the most distinctive cultures in Bhutan, characterised by distinctive conical bamboo hats worn by women.
For visitors who make the effort, Gasa offers experiences unavailable anywhere else in Bhutan: natural hot springs with medicinal properties, the Royal Highland Festival, the dramatic Gasa Dzong perched above the valley, and the trailhead for treks into some of Bhutan's wildest and most beautiful territory.
Must-See Places in Gasa
Gasa Tshachu — Natural Hot Springs
The Gasa Tshachu are Bhutan's most celebrated natural thermal springs, believed to cure 13 different diseases — a healing tradition known as Neyrig Chusum. The springs sit on the bank of the Mo Chhu river at 2,100m, approximately 2km from Gasa Dzong. They were destroyed by a catastrophic Mo Chhu flood in 2021 and rebuilt over two years, reopening on 14 October 2023. The rebuilt complex has 10 bathing pools — five for women and five for men — plus two VIP pools, each at a different temperature and believed to treat different conditions. The origin of the springs is traced to the 13th-century saint Drubthob Terkhungpa, who is said to have dispersed 128 types of medicine throughout Gasa, from which 128 hot springs and medicinal springs originated.
Gasa Dzong
Perched dramatically on a ridge at the entrance to Gasa town, Gasa Dzong was built in the 17th century by the Zhabdrung Ngawang Namgyel as a defensive fortification against Tibetan invasion. The dzong is smaller than the great fortresses of western Bhutan but equally dramatic in its setting — commanding views north towards the Tibetan border and south down the Mo Chhu gorge. The dzong remains an active administrative and monastic centre. The annual Gasa Tshechu festival is held here each December.
Royal Highland Festival (October)
One of Bhutan's most extraordinary cultural events, the Royal Highland Festival is held annually at Gasa in October to celebrate and preserve the culture of Bhutan's highland nomadic communities — the Layap and Lunap peoples. The festival features yak racing, traditional Layap dances and music, archery competitions, and a spectacular parade of traditional dress. It is a genuine celebration of living highland culture rather than a tourist performance, and one of the most authentic festival experiences available in Bhutan. Accommodation in Gasa is limited during the festival — advance booking is essential.
Laya Village & Trekking
Laya, a high-altitude village at approximately 3,820m inhabited by the distinctive Layap people, is reached by a 2–3 day trek north from Gasa through some of Bhutan's most pristine wilderness. Laya women are immediately recognisable by their unique conical bamboo hats and distinctive dress. The village offers a rare glimpse into a semi-nomadic Himalayan way of life that has remained largely unchanged for centuries. The trek to Laya is part of the legendary Snowman Trek route — completing it as a standalone journey is one of Bhutan's finest trekking experiences.
Jigme Dorji National Park
Gasa district contains a large portion of Jigme Dorji National Park — Bhutan's second-largest protected area and one of the most biodiverse in the Himalayas. The park is home to snow leopard, blue sheep, red panda, takin (Bhutan's national animal), musk deer, and over 300 bird species. The park also encompasses the Snowman Trek route — widely regarded as one of the world's most challenging high-altitude treks — which passes through Gasa and Laya before crossing glacial passes above 5,000m into the remote Lunana district. For wildlife enthusiasts, the forested hills around Gasa town offer frequent sightings of takin and Himalayan bird species.
Cordyceps Harvest & Highland Economy
Each summer, the alpine meadows above Gasa and Laya become the site of one of Bhutan's most economically significant annual events: the harvest of Cordyceps sinensis — a parasitic fungus that grows from the bodies of ghost moth caterpillars at elevations between 4,000 and 5,000 metres. Known locally as yartsa gunbu (meaning "summer grass, winter worm"), Cordyceps is highly valued in Traditional Chinese and Tibetan medicine and commands extraordinarily high prices — up to USD 50,000 per kilogram at the upper end of the market. For highland families in Gasa and Laya, the Cordyceps harvest provides the majority of their annual cash income and funds education, home renovation, and the purchase of yak stock. Visiting Gasa in late May or June, when the harvest is underway, offers a fascinating glimpse into this high-stakes, high-altitude seasonal economy. Bhutan's government tightly regulates the harvest season and collection zones to prevent over-harvesting.
Getting to Gasa
From Punakha
Gasa is approximately 47 km north of Punakha — a 3–4 hour drive on a road that is paved for the first section and becomes unpaved (but negotiable by SUV) as it approaches Gasa. A 4WD vehicle and experienced mountain driver are essential. The drive follows the Mo Chhu river gorge northward through breathtaking scenery.
Hot Springs Access
The Gasa Tshachu hot springs are located approximately 2 km from Gasa Dzong, accessible by road. A short walk from the road leads down to the springs on the riverbank. The springs are open year-round though water levels are higher and access may be affected during monsoon (June–August).
Where to Stay
Accommodation in Gasa is very limited — a small number of guesthouses and a basic tourist facility near the hot springs. Most visitors to Gasa make it a day trip from Punakha. For Royal Highland Festival visits, a tented camp is typically set up — book through Found Bhutan well in advance as spaces are limited.
Weather
Gasa is cold — at 2,700m with cold air flowing south from the Tibetan Plateau. Summers (June–August) are cool and rainy. The best months are April–June and September–November. October is festival season. Winter (December–February) is cold but clear and the hot springs are at their most appealing.
Gasa — The Sacred North
Gasa's history as a distinct administrative district is relatively recent, but its sacred geography reaches back much further. The 13th-century Tibetan saint Drubthob Terkhungpa — the same figure associated with the founding of Nabji Lhakhang in Trongsa — came to Gasa and meditated extensively in the valley. He is credited with discovering and blessing the hot springs, distributing medicinal herbs across the highland landscape, and establishing the sacred character of the Mo Chhu gorge. Centuries later, in 1646, the Zhabdrung Ngawang Namgyel built Gasa Dzong directly above Terkungpa's old meditation site to defend Bhutan's northern frontier against Tibetan invasion — a purpose it served successfully through several attempted incursions in the 17th and 18th centuries.
The Layap people of Laya village (3,820m) represent one of the most culturally distinct communities in Bhutan. Semi-nomadic yak herders, they move with their animals between highland pastures in summer and lower valleys in winter. Layap women are immediately recognisable: they wear conical bamboo hats with a spike at the top, black woollen jackets with silver trim, and long striped woollen skirts. They carry their hair long and wear extensive silver jewellery accumulated over a lifetime. The Layap dialect is distinct from standard Dzongkha. Their primary economic activities are yak husbandry — producing milk, cheese, butter, hair textiles, and meat — and the harvest of Cordyceps, the high-value medicinal fungus that grows in the alpine meadows above Laya each summer.
The Royal Highland Festival, held annually at Laya in October, was established to celebrate and preserve this highland culture and to generate sustainable tourism income for the communities who live here. It features yak and horse shows, traditional Layap dances and songs, archery, and a parade of traditional dress from Laya, Lunana, and other highland communities. It is one of the most visually spectacular cultural events in Bhutan.
