Ak-Suu Traverse (Tien Shan)

The Ak-Suu Traverse is one of Kyrgyzstan’s flagship multi-day treks in the Terskey Alatau range (Tien Shan), near Karakol and Issyk-Kul. This strenuous 110km journey is a definitive high-altitude experience, transitioning from the flower-filled meadows of Jyrgalan to the dramatic granite spires of the Karakol Valley and the turquoise waters of Lake Ala-Kul. Historically a corridor for semi-nomadic Kyrgyz shepherds, the route is known for long days, multiple passes exceeding 3,800m, and significant vertical gain. It is widely regarded as the premier long-distance challenge in the region, requiring self-sufficiency and experienced navigation. Unlike standard valley walks, the traverse crosses several distinct climatic zones, including ancient spruce forests and glacial basins. Practical planning must account for complex river crossings in the afternoon silt-flows and the high micro-climate volatility of the 'Heavenly Mountains'.

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.
