Illampu Circuit

The Illampu Circuit is a demanding 6-to-7-day trek that circumnavigates the northern giants of the Cordillera Real: Illampu (6,368m) and Ancohuma (6,427m). Often described as one of Bolivia's most vertically significant non-technical routes, the loop starts and ends in the sub-tropical town of Sorata (2,700m). Much of the circuit sits above 4,000m once the Sorata valley is left behind, crossing multiple high passes including the Abra de la Calzada (~5,045m). The route crosses high-altitude pampas inhabited by Aymara herders and traverses rugged moraine fields directly beneath active glaciers.

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.
