Cordillera Apolobamba Traverse

The Apolobamba Traverse is a remote, high-altitude backpacking route in the northern Bolivian Andes. Spanning approximately 92km between the villages of Pelechuco and Curva, the trek crosses the ancestral territory of the Kallawaya people—traditional herbalists recognized by UNESCO. The route follows ancient stone paths and animal trails, staying almost exclusively above 4,200m. It traverses several high passes, including the 5,100m Sunchuli Pass, offering direct views of the 6,000m peaks of the northern Apolobamba range. Due to its distance from major cities, it remains one of the least-trafficked and most preserved regions of the Bolivian Andes.

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.
