Jhomolhari - Laya Gasa Trek
Twelve days from Paro to the hot springs at Gasa
The classic long route: up to Jangothang, north along the Tibetan border through Lingshi and Laya, and out at the Gasa hot springs.
This is the big one. Twelve days walking from the Paro valley to Gasa, keeping close to the Tibetan border for much of it, crossing four passes over 4,700 m and reaching Laya at 3,840 m, a yak-herding village four days from the nearest road, where the women wear conical bamboo hats and the houses are built for winter.
The first four days are the Jhomolhari route: up the Paro Chhu, two nights at Jangothang under the north face. Then it turns north over Nyile La to Lingshi, and works east through Chebisa, Shomuthang and Robluthang, over Sinche La at about 5,000 m, and down to Laya.
From Laya it is two days down to Gasa, where there are hot springs at the bottom, which is a well-timed thing to find after twelve days.
This is a serious trek. It is remote, the weather is genuine, and there is no road access for a week in the middle.
What stands out
- Two nights at Jangothang under the north face of Jhomolhari
- Lingshi Dzong on its spur, with Tserim Kang behind it
- Laya, a genuine yak-herding village at 3,840 m, four days from a road
- The hot springs at Gasa on the last day of walking
