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 GR R2 is a legendary long-distance trail that traverses the French island of Réunion in the Indian Ocean from north to south. It is widely considered one of the most physically demanding GR trails in the French network due to its extreme verticality and tropical environment. The route crosses the three massive 'Cirques' (natural amphitheaters), climbs the highest peak in the Indian Ocean (Piton des Neiges, 3070m), and borders the active volcanic zone of Piton de la Fournaise.
