Piuquenes Pass (Andes Crossing)

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.

Quilotoa Loop and Emerald Lagoon. The Quilotoa Loop is a multi-day trek through the central Ecuadorian Andes, a Commonly Recognized Trek notable for its blend of high-altitude geography and indigenous culture. The journey typically spans 3-4 days through villages like Sigchos, Isinlivi, and Chugchilán, culminating at the water-filled Quilotoa caldera. The 3km-wide crater features a 250m-deep turquoise lagoon formed by a volcanic eruption 800 years ago. Hikers can choose between the full village-to-village 'Loop' or a 12km rim circuit.
