Laguna 69

The high altitude color shock. Laguna 69 is an intense day hike in the Huascarán National Park, starting from the Cebollapampa base (3,900m) and climbing to 4,600m (15,090ft). The reward for this grueling ascent is a high-altitude glacial lake with a color so vibrant blue it looks neon. Located at the foot of the massive ice-covered peaks of Huascarán and Chacraraju, the lake is fed by a spectacular waterfall cascading from the ice above. It is a rite of passage for every trekker visiting Huaraz.

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.
