Gasa Tshachu (hot springs)

Gasa Tshachu, also rendered Gasa Tshachhu or the Gasa hot springs, is a group of natural thermal springs in Gasa Dzongkhag in northern Bhutan. Situated near the bank of the Mo Chhu (Mo Chhu river) below Gasa Dzong, it is one of the most renowned and widely visited tshachu — medicinal hot springs — in the country, drawing Bhutanese pilgrims and bathers from across the kingdom, particularly in winter.^[1]

In Bhutanese tradition tshachu are regarded as therapeutic waters whose mineral content and blessings relieve ailments ranging from arthritis and joint pain to skin conditions and body aches. Gasa Tshachu is especially esteemed, and is associated in popular belief with the healing of a number of distinct illnesses.^[2]

Origins and tradition

The origin of the Gasa springs is traditionally attributed to the 13th-century treasure-revealer Drubthob Terkhungpa, who is said to have dispersed many varieties of medicinal substances across the Gasa area, giving rise to its hot springs (tshachu) and cold medicinal springs (menchu).^[2]

The springs are also linked to Zhabdrung Ngawang Namgyal, the unifier of Bhutan, who according to tradition entered the country through Gasa around 1616 and rested at the tshachu, where the waters are said to have eased his joint pain and fatigue before he continued onward. The site has remained a place of both pilgrimage and convalescence ever since.^[1]

Destruction and reconstruction

In 2021 a flood on a swollen Mo Chhu washed away the hot-spring complex. After roughly two years of reconstruction, the rebuilt Gasa Tshachu was reopened to the public in October 2023, restoring access to one of the country's most popular thermal-spring sites.^[3] The springs lie within reach of Gasa town and the lower stages of the Laya–Gasa trek, and visiting them remains a long-established part of winter travel in the region.
