Bhutan’s mountainous terrain’s offer a fascinating adventure for bicycling enthusiast. The route along Bhutan’s West-East Highways (approx. 600kms) is an exciting route with challenges of surmounting a new pass over 3000 meters every day. The highways winding up an shown mountains with drops of thousand of feet keep one too high an adrenaline to feel the slightest pinch of monotony. As one progress along the route, there is a discernible change in the flora and temperature when one gradually descends, from the aping height, into the temperate regions of the east. All along the route the interruption by picturesque, and almost medieval, villages and towns rich in cultural spots make a welcome diversion.
