Tourism in Gilgit-Baltistan, an administrative unit of Pakistan, focuses on the mountains. Gilgit-Baltistan borders Pakistan's Khyber Pakhtunkhwa Province to the west, a small portion of the Wakhan Corridor of Afghanistan to the north, Xinjiang, China to the northeast, the Indian territory Jammu and Kashmir and Ladakh to the southeast, and the Pakistani-administered state of Azad Kashmir to the south.
Gilgit-Baltistan is home to five of the "eight-thousanders" and to more than fifty peaks above 7,000 metres (23,000 ft). GilgitAstore and Skardu are the three main hubs for expeditions to those mountains. The region is home to some of the world's highest mountain ranges. The main ranges are the Karakoram and the western Himalayas. The Pamir Mountains are to the north, and the Hindu Kush lies to the west. Amongst the highest mountains are K2 (Mount Godwin-Austen) and Nanga Parbat, the latter being one of the most feared mountains in the world.
Three of the world's longest glaciers outside the polar regions are found in Gilgit-Baltistan: the Biafo Glacier, the Baltoro Glacier, and the Batura Glacier. There are, in addition, several high-altitude lakes in Gilgit-Baltistan.
