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.

Route Typology: Developed Boardwalk / Managed Nature Walk. Sendero el Perezoso (The Sloth Trail) is a short boardwalk loop in Manuel Antonio National Park designed to be accessible, though conditions may vary depending on maintenance and crowd levels. This trail is engineered for high-probability wildlife viewing in a shaded, secondary forest environment. It is an ideal introductory walk for families and photographers, leading from the park entrance toward the primary beach zones. It is widely considered one of the most reliable locations in the Puntarenas Province to observe both two-toed and three-toed sloths in their natural canopy habitat.
