The Pakistani definition of a mountain according to the Ministry of Tourism in Islamabad is a peak higher than 6500 meters, 21,450 feet. Therefore you dont need permits for peaks lower than that mark. Anything higher, or if you are hiking within 20 km of an international border you will need permits. For a permit, you need to either: 1. Licensed mountain guide OR 2. Pakistan Army Liason Officer (LO) to guide you along the way. The guide/LO has to be equipped with gear that will allow him to hike with you till the base camp of your peak.

The Hispar Mustagh is a collection of big snowy peaks such as Trivor and Disteghal Sar , Mohmil Sar near the snout of the Hispar Glacier an a series of rock towers such as the Latok Group, Baintha Brakk, Sosbun Brakk, and more.
For the rock towers its best to trek up the Biafo Glacier, which can be reached from Askoli in one day. For the larger peaks its logistically simpler to either access from the Mohmil glacier in Shimshal valley or to approach from the village of Nagar.
