Gasa Tashi Thongmon Dzong — Built on a Goddess

The founding of Gasa Dzong begins with a 13th-century meditation cave. Drubthob Terkungpa, a Tibetan Buddhist saint, established his cave in what is now Gasa in the 1200s. The area took the name Gasa — meaning “the land of a blacksmith” — from Drupthop Terkungpa, who was skilled in metalwork. Four centuries later, Zhabdrung Ngawang Namgyal commanded his second Druk Desi, Tenzin Drukdra, to build a dzong directly above this cave, on the hillock that forms the “chest” of the landscape deity Tsheringma — the Goddess of Long Life whose body the entire valley landscape is said to represent. The dzong was completed in 1646 and named Tashi Thongmon in 1648 after its protective deity, following a vision in which Zhabdrung gave Damchen Gomo, the local deity, this new name.

The circular plan of the dzong is its most architecturally distinctive feature. Every other major dzong in Bhutan — Punakha, Thimphu, Paro, Trongsa, Jakar — is rectilinear in plan, following the standard Bhutanese fortified monastery form. Gasa is round. This is partly a consequence of the hillock it occupies and partly the result of the defensive function it was designed for: the circular exterior, ringed by watchtowers at intervals, allowed defenders to cover all approaches without blind angles. The dzong defended successfully against multiple Tibetan invasions in the 17th and 18th centuries. On clear days, the summit of Mt Gangboom is visible from the dzong’s upper terrace.

The Layap People — Highland Nomads of the North

Gasa district is home to the Layap people — semi-nomadic yak herders who live in the highland villages of Laya (3,840m) and Lungo, above the treeline in the high valleys north of the dzong. The Layaps are one of Bhutan’s most culturally distinctive communities. Their livelihood centres on yak husbandry: the animals provide milk, cheese, butter, meat, and hair fibres for weaving. The yak hair textiles of Laya are sold throughout Bhutan. The Layaps also harvest Cordyceps — the high-altitude medicinal fungus of extraordinary commercial value, used in traditional Chinese and Tibetan medicine — which grows in the alpine meadows around their villages in summer.

Layap women are immediately recognisable by their distinctive dress: a tall conical bamboo hat worn tilted forward, a striped woven jacket fastened at the waist, and multiple strands of coral and turquoise jewellery accumulated over a lifetime. The hat style is specific to the Layap community and found nowhere else in Bhutan. The Tshechu is one of the few occasions in the year when the Layap community descends to lower elevation in large numbers, making the Gasa festival the best opportunity for most visitors to encounter them.

The Gasa Hot Springs

Two hours’ walk below the dzong, at 2,100m on the bank of the Mo Chhu river, lie the Gasa Tshachu — the most celebrated hot springs in Bhutan. The water is believed to cure 13 different types of diseases, and the springs attract Bhutanese pilgrims and international visitors year-round. The springs are divided into separate pools of varying temperatures; the water is geothermally heated by volcanic activity deep below the valley floor. A visit to the springs after the Tshechu — soaking tired legs in geothermal water while the Mo Chhu runs past below — is one of the most pleasurable activities in the Bhutanese festival calendar.

Nearby, at Panikong village, is Tshechu Dra — a sacred cliff where Guru Rinpoche is said to have extracted longevity water from the rock face. The cliff is a pilgrimage site for those seeking long life and good health.

The Snowman Trek and the Royal Highlander Festival

Gasa is the southern gateway to two of Bhutan’s most celebrated adventure experiences. The Snowman Trek — widely regarded as one of the world’s most challenging high-altitude trekking routes — begins in Gasa and passes through Laya and the remote Lunana district, crossing multiple glacial passes above 5,000m before ending at Nikachhu. The full route takes approximately 25–30 days. Only a small number of trekkers complete it each year.

The Royal Highlander Festival, held annually in the highlands above Gasa, celebrates the culture and traditions of the Layap, Lunap, and Brokpa nomadic communities. It features yak races, highland sports, traditional dress competitions, and folk performances specific to these high-altitude communities. Combining the Gasa Tshechu (autumn, at the dzong) with the Royal Highlander Festival (also autumn, in the highlands) in a single visit gives the most complete picture of Gasa’s extraordinary cultural landscape.
