Gasherbrum I, also known as Hidden Peak, is located at 8,080 meters above sea level in the Gilgit-Baltistan region of Pakistan. The mountain is beautifully nestled between a labyrinth of high peaks in the Karakoram Mountain range. Gasherbrum I is known for its challenging topography and is the tallest of the six Gasherbrum peaks in the area.
In 1936, veteran mountaineer H. De Segogne led a team of French climbers in an attempt to summit Gasherbrum I, but they were unsuccessful. However, in 1958, Nich Clinch and his team of American climbers became the first to reach the summit. The route to the base camp of Gasherbrum I begins in Skardu. You’ll travel through Shigar Valley and then trek across the Baltoro Glacier to finally reach the base camp. The climbing season for Gasherbrum I typically runs from June to August.
