Bhutan’s rugged terrain and peaceful roads make its mountain biking or cycling tour a bit more exciting than most other events. You can cycle on the hilly motor roads or there are several new off-road biking tracks being developed. The Tour of the Dragon is one of the most popular biking trips in Bhutan and runs from Bumthang to Thimphu, covering over 260 kilometers in a day. It normally takes place in mid-fall. The best seasons for mountain biking trips are spring and fall.
