This trek is an extension of Jhomolhari trek and offers diverse flora and fauna, including a good opportunity to spot blue sheep. The trek starts from Drugyel Dzong to the isolated valleys of Lingzhi, up to the Laya region at 4,000 meters (over 13,000 feet), where yak-herders live at the foot of Mt. Masagang, at 7,200 meters (23,620 feet) and the sub-tropical Punakha valley at 1,300 meters (4,265 feet).

Lingzhi played an important role in controlling travel over Lingzhi la between Bhutan and Tibet. Goyak is another pleasant settlement; a compact village of stone houses clustered together which is very unusual in Bhutan. Also, watch for bearded vultures and Himalayan Griffons flying overhead.

There are several large herds of blue sheep living in the rocks and you are sure to spot one on this trail. Tsheri Jathang, a Takin Sanctuary where herds of Takin [Bhutans National animal] migrate during summer and remain for about 04 months. You can see classic examples of lateral moraines where the glacier has pushed rocks up on both sides. Views of different peaks and mountains are just fabulous and probably the best that you can see from any other part of the country.

It also introduces you to the unusual culture of Layap people and offers a stop at a natural hot spring in Gasa. The Laya women wear black yak-hair costumes and conical bamboo hats, a very distinct traditional costume worn nowhere else except Laya. Laya route passes by hot springs and Gasa Dzong, and through different levels of vegetation. This trek combines a variety of landscapes, villages, and majestic views of peaks.
