Bhutan's mountainous terrains offer a fasinating adventure for bicycling enthusiasts. The route along Bhutan's west - east highway(approx. 600 kms) is an exciting route with challenges of surmounting a new pass over 3000 meters everyday. The highways winding up and down with drops of thousands of feet keeps one too high an adrenalin to feel the slightest pinch of monotony.

As one progresses along the route, there is a discernible change in the flora and temperature when one gradually descends from the alpine heights intothe temperature regions of Punakha, Wangdiphodrang, Mongar, Trashigang and Samdrup Jongkhar. All along the route the interruption by picturesque and almost medieval villages and towns rich in cultural sopts make a welcome diversion.
