A very scenic and moderate trekking trip to remote and seldom visited areas of the beautiful Yasin Valley and over Thoi Pass (4499 m) to Yarkhun Valley in the Hindukush Range tracing back one of the ancient trade routes. An interesting jeep drive from Gilgit to Yasin Valley and further to the road head at Nialthi takes us to the starting point of this spectacular trek. A daily 5-6 hrs walking through fields, bushes, wildflowers, and glaciers takes us gradually over Thoi Pass provides superb views countless peaks around 6000 m, wide green meadows in the foreground and Aghost Bar glacier snaking down to Thoi Valley.
