Got up early morning, took bike from rental shop and headed towards Bumla pass. it took me around 3 hours to reach there, as I was going bit slow while taking halt again n again to capture landscape in my eyes. Special permit is needed to visit there sometimes as the place is bit critical. Road is not so good, avoid visiting Bumla pass on 2-wheeler during rainfall or snowfall. Tawang is a town which is surrounded by International borders from the 3 sides. 2 sides bordering with Bhutan, 1 side with China. Bumla is situated at an altitude of around 15780 ft which I checked on Apple compass. Bumla pass was the road used by Dalai lama while escaping from Tibet to enter in India. The place is damn beautiful, you can feel the thrill on the route of Tawang, that's actual an adventure. If your body will not acclimatized, you may find some difficulty over there. So, do carry Tablet of Diamox with you.
