Cerro Chirripó (Chirripó National Park)

Route Typology: High-Altitude Páramo Ascent. Cerro Chirripó is Costa Rica's highest mountain (3,820m) and the center of the Chirripó National Park. The ascent involves a significant 2,000m vertical gain, transitioning from tropical oak forests at the base into the unique high-altitude páramo—a shrubland ecosystem of glacial origin. Widely considered the most physically demanding established trek in Costa Rica, it is typically broken into two days with an overnight stay at the Refugio Crestones. On rare clear mornings, the summit offers a simultaneous view of both the Caribbean Sea and the Pacific Ocean.

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.
