The major attractions apart from the mountain scenery and Shyok river basin to this region are cold desert and bactrian camels of Hunder and hot water springs of Panamik. Yes, there is a desert with sand dunes around Diskit and Hunder which host bactrian camels who have two humps reminding us of old times when this region was a part of Silk Route to Central Asia. Panamik hot springs are not that great with not very great amount of water oozing from mountain cervice at around 60-70 degree.
