Mountain biking is a new sport in Bhutan, but is gaining popularity with both Bhutanese and expats, who have recently organized the Bhutan Mountain Biking Club. Some adventure travel companies have organized trips that allow bikers to bring their own cycles and travel through­out Bhutan accompanied by a 'sag wagon' for support. Long journeys are difficult be­cause there's a lot of uphill peddling and ap­proaching vehicles roar around corners, not expecting cyclists. Local cycling excursions in the Paro, Thimpu and Bumthang valleys offer a safer and less strenuous mountain-biking experience.
