Lukpe La Pass 5833 meters lies in central Karakorum. It connects the Biafo Glacier and Snow Lake in the south with the Braldu Glacier in the north to form an ice stream over 100 kilometers long. The tour through this remote area is one of the greatest adventures you can experience as a passionate trekker.

The Biafo Glacier is a 63 km long glacier in the Karakoram Mountains of Gilgit Baltistan, Pakistan which meets the 49 km (30 mi) long Hispar Glacier at an altitude of 5,128 m (16,824 ft) at Hispar Pass to create the world’s longest glacial system outside the polar regions. This highway of ice connects two ancient mountain kingdoms, Nagar (immediately south of Hunza) in the west with Baltistan in the east. The traverse uses 51 of the Biafo Glacier’s 63 km and all of the Hispar Glacier to form a 100 km glacial route.

Snow Lake is located 16,000 feet 4,877 m above sea level and is approximately 10 miles 16 km wide. The basin lies at the head of the Biafo and Hispar glaciers, which spread down from the Hispar Pass in opposite directions, forming a 100 km river of ice that is among the world`s longest continuous glacier systems outside of the polar regions. The central Karakoram, first explored and mapped in 1937 and 1939, is perhaps the wildest of all. It is an area of vast glaciers, high mountains, and remote passes.

The length of Biafo Glacier is 68 kilometers 42 miles long with a total area of 625 sq. km. It starts at Korofong above Askole village. Hisper Glacier is 52 Kilometers long. It is only the Hisper pass, which separates the Hisper Glacier and Biafo Glacier. However, most geographers consider the two glaciers as one; they call the Biafo-Hisper Glacier. If that be so then the 120 kilometers 75 miles long biafo Hispar Glacier probably becomes the second longest glacier in the world.

Approaching Snow Lake following a broad highway of Ice, a huge glaciated basin at 4500 meters, there could be a couple of crevasse areas where it will be necessary to rope up. Here we have the opportunity to view Biantha Brak, (7284 m), Snow Lake Peak, and Simkiang Glacier. From here we ascend the Hisper La and camp on the summit, which gives us panoramic sunset and sunrise views of the whole Biafo – Hispar.
