The Snow Lake Trek , also known as the Biafo-Hispar Trek is one of Pakistan's greatest treks. It has been rated as one of the top five treks in the world for its extreme beauty and adventurous nature.
Biafo Hisper trek starts from Skardu –Askoli.. The trek from Askole initially proceeds towards K2, then turns northwest up the Biafo Glacier to Snow Lake. The route is formed by the Biafo and Hispar Glaciers which form the longest continuous stretch (114km) of glacier in the Karakorums. This icy highway takes trekkers deep into the mountains towards Snow Lake, the large glacial basin formed by the Lukpe La and Sim Glaciers.
Most groups start this trek from the village of Askole in Baltistan's Shigar Valley and end in the village of Hispar in the Nagar Valley. Over two-thirds of the trek is on glacier, which can be very demanding, but most campsites are off the glacier in beautiful meadows with impressive.
Trekking across Snow Lake requires traveling in roped teams due to the danger of hidden crevasses, but the walking is not difficult. Crampons are not needed, but because the route can be difficult to follow, an experienced guide is necessary. This is also one of the longest treks in Pakistan. From Gilgit to Gilgit it normally requires at least 16 days depending on fitness and weather. The descent differs from the ascent, going through the Hunza Valley and ending in Gilgit.
