One of the most strenuous but equally rewarding walk of over on hundred kilometer traverse, of Biafo and Hisper Glacier, passing through 30 square miles and 1.5 km thick now Lake. The huge glacial systems of the Central Karakoram presented explorers, with formidable challenges, right up until the 1930’s when Eric Shipton forged a link over Karakoram watershed, to the Shaksgam Valley in Xinjiang. Our trek will capture something of this pioneering spirit, as we traverse the Biafo and Hisper glaciers, and explore the main divide of the Inner Karakoram. From Askole we follow the first few stages of the K2 trek before diverting up the Biafo Glacier. The route provides breath-taking views of Ogre, Latoks and countless unclimbed peaks, as we walk over cracking glacier.
