The first part of the Laya Gasa Trek goes along the same route as the Jomolari Trek I right till Lingshi. Besides the unforgettable views of Mount Jomolhari, the trek offers spectacular views on Jichu Drake, Gangchhenta (Great Tiger Mountain). Between Jangothang and Laya the trail hardly goes below 4,000m and one has good opportunities to spot blue sheep or even takin. Some beautiful Bhutanese mountain villages, the unique culture and appearance of the Layaps (people of Laya district) and finally a day of relaxation at the Gasa hot springs add to an extremely rewarding trekking experience. All in all, the Laya Gasa Trek is considered to be the most beautiful trek of Bhutan, only to be beaten by the tough Snowman Trek.

Cross an army outpost along the way and enjoy a spectacular view of high mountain ridges and snow-capped peaks. Yaks and the herder’s homes become a regular feature of the landscape. Passing the villages Soe, Takethang and Dangochang is another asset on this day. Reaching Jangothang, one of the most beautiful campsites of the Himalayas, you will again have a spectacular view of Mount Jomolhari.

On the way down to the camp you will pass by some of the yak herder’s tent, made from yak wool, where the herders take shelter while on the move to various pastures for their yaks. As you come down into the Lingshi basin, you get a wonderful view of Lingshi Dzong on a clear day. Tserimgang and its glaciers rise up at the north end of the valley.

Right behind the stone house you will see an impressive terminal moraine and a glacial lake at the foot of the valley. You can see classic examples of the lateral moraines where the glacier has pushed rocks up both sides of the valley. Below the moraine, you cross the Kango Chhu and soon reach the Limithang campsite.
