Chelela, at 3822m/12,539ft is the highest motor able pass in Bhutan and is flanked by Paro and Haa districts. This pass is along the forsaken ancient trade route. The drive itself is scenic with stunning panoramic view of the two valleys and snowcapped Himalayan mountains. You can also opt for the Chelela ridge hike that takes about 3-5 hours. The hike follows the trail used by yaks and yak herders through forests filled with many species of Primula, junipers, firs, pine, oaks and shades of red and orange rhododendrons. The short steep descent from the top will take you to the nunnery of Kila Goemba. The community is one of the oldest of seven nunneries in Bhutan, and was initially established in the early 9th century as a meditation site. After being destroyed by fire, the temple was rebuilt and officially established in 1986 as an Anim Dratshang (religious community of Buddhist nuns).
