This trek is one of the most challenging treks available in Bhutan and route partially overlaps with the trail of the legendary Snowman Trek, the most difficult trek in the world. This grueling nine days journey will take you up to the Duer Hot springs, arguably the most beautiful hot springs in the Himalayas.

The trail has numerous steep ascents and descents and ranges from altitudes between 3000-4700 m. However despite the difficulty this trek is well worth the effort as it will take you through some of the most beautiful landscapes in Bhutan. You’ll journey through forests of spruce, hemlock, juniper and maple, through regions populated by herds of Blue Sheep, Musk Deer and even Himalayan Black Bears.

The entire day will be dedicated to resting in the hot springs. The periods between March to April and September to November are the best times to take on this challenging route.

Day 1: Duer – Gorsum (Distance 18 km, six to seven hours, 380 m ascent, camp altitude 3,120 m). The trek route follows the Yoleng Chhu, a river known for its abundance of trout. The trail from Bumthang to Gorsum is a gradual climb.

Day 2: Gorsum – Lungsum (Distance 12 km, five hours, 40 m ascent, camp altitude 3,160 m). The trail leads through a dense forest of Spruce, Hemlock, Cypress, Juniper and Maple. The trail ascends gradually to the campsite.

Day 3: Lungsum – Tsochenchen (Distance 15 km, -six to seven hours, 620 m ascent camp altitude 3,780 m). The vegetation along the trekking route is similar to places crossed the previous day. Near the campsite the vegetation thins out and the camp is made above tree line.

Day 4: Tsochenchen – Duer Tsachu (Distance 18 km, eight to nine hours, 1,340 m as­cent, 1,530 m descent, camp altitude 3,590 m). The trek from Tsochenchen is uphill all the way till Juli La (4,700 m). If the day is clear, you will have a great view of the surrounding mountains from the pass. After crossing the pass, the trail descends to a lake at 4,220 m, then climbs again to Gokthong La (4,640 m). From here it is a steep way down till the campsite. Musk deer, herds of blue sheep and Himalayan bear is sometimes seen along the route.
