I was sent on this trek, on assignment, by Bikat Adventures (https://www.bikatadventures.com/) as a part of my internship and at 16 years of age it was the best trip ever. How many 16 year olds do you know who have climbed an actual mountain, at 15,000 feet I was at the highest point in my life. The trek offers some of the best views, one could ask for. At some points of the trek it was almost as if I were in a foreign land or the sets of a Hollywood movie. This trek is a must for adventure freaks and photographers. Along with rough terrain the trek offers a ton of eye candy and no image can do justice the place. My attempts aren't even close to the first hand experience. The Rupin pass trails crosses between two states, Himachal and Uttrakhand. Rupin pass is one of those heavenly places that reignite your faith in the divine. The experience itself is enough to instill a new life into a corporate corpse.
