Karnak Valley, also known as Chang Chu, is in Ladakh, Leh District of Jammu and Kashmir. This valley is a beautiful camping site. Sumdo is at the end of Karnak Valley. Nearby is Dhat, one of the largest villages in Rupshu - the region of great lakes. The valley once belonged to Ladakh’s richest monastery in Hemis. It is a broad valley bounded by hills and cliffs. The lower half of the valley is not inhabited and thus forms a ready-made core area for the Hemis High Altitude National Park.
