This is a moderate four-day trek in the Lahaul-Spiti district of Himachal Pradesh, leading to the large, high-altitude Chandra Tal Lake (Lake of the Moon in the local dialect). The landscape and the scenery changes ever so quickly, with each sight more beautiful than the one before – until you reach the lake, that is. The world comes to a stand still at Moon Lake, a turquoise crescent of water surrounded by the Chandrabhaga & Mulkila Massifs.
This trek takes you from the lush green Kullu Valley to the dry and cold desert of the Lahoul Valley before concluding at the magnificent High Alpine Lake of Chandra Tal or Moon Lake (4000 m). This is one of the most popular treks in the Western Himalayas because of several reasons. It remains open for maximum period of the time, one can end it after Chandra Tal and go to Spiti Valley and one is free to come back to Manali or go to Leh or trek further into Zanskar Valley. Secondly, it is the combination of the green area of Kullu Valley, challenging passes like Hamta and high altitudes of Topko Gogma with facing mountain peaks of CV ranges, beautiful Chandratal Lake and lot more.
