Of all the destinations that I have been to so far, North Sikkim demands fearlessness and patience like no other. It certainly isn't the right place for the fainthearted souls. The treasures held in the pristine land of North Sikkim deserve more words of praises than I can ever come up with. Read on and you'll know that I am not exaggerating at all. I hope you soon make it here and you shall realize why it feels like more of an accomplishment and you will let yourself this feeling sink in.Gurudongmar Lake is set at an altitude of 17,800 feet- where the level of oxygen dips substantially and the temperature is always subzero (less than 0 o C). The moment you reach this place, you would want to simply pause and savor Nature's beauty at its best. I'm sure you must have heard about the Teesta River. Gurudongmar Lake is the source of this river. If you happen to have enough time at hand, you can even for go for river rafting on the Teesta River.
