The Jomolhari trek is one of the most popular treks in Bhutan. It starts from the Paro valley and ends in Thimphu. This trek has some of the most amazing views of Mount Jomolhari (7,314 m/23,996 ft), one of the holiest mountains in Bhutan. The duration of the trek is over a period of 9 days, with the route passing through two high altitude passes, the Yale La (4,950 m/16,240 ft) and the Nyele La (4,890 m/16,043 ft), which makes this trek a bit strenuous. The best season to go on this trek is from April to June and September to November.
