Lost City Trek (Ciudad Perdida)

Route Typology: Guided Jungle Expedition. The Lost City Trek leads to 'Teyuna', an archaeological site of the ancient Tairona civilization built around 800 AD. Located deep in the humid heart of the Sierra Nevada de Santa Marta (a UNESCO Biosphere Reserve), the 44km route involves a cumulative vertical strain of 2,700m. The final approach requires a climb of 1,200 ancient stone steps. While the max altitude is only 1,200m, the primary challenge is the extreme tropical humidity (often 90%+) and consistent heat, paired with steep, muddy jungle ridges and river crossings.

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.
