Baltoro Glacier & K2 Base Camp

The Throne Room of the Mountain Gods. The trek to K2 Base Camp via the Baltoro Glacier is a monumental 140km journey into the heart of the Karakoram. Starting from the village of Askole, the trail winds up the massive Baltoro—one of the longest glaciers outside the poles—passing under the sheer granite cathedrals of Trango Towers and Cathedral Peak. The climax is Concordia (4,700m), the meeting point of the Baltoro and Godwin-Austen glaciers, where you are surrounded by the highest concentration of high peaks on Earth, including four 8,000m summits: K2, Broad Peak, and Gasherbrum I & II.

Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.
