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.

It is remarkably rare for a major European capital to have a pristine expanse of ancient primeval forest just 20 kilometers from the city center. Tyresta National Park is Stockholm's wilderness backyard. The premier hike is the purple-blazed Tyrestarundan (The Tyresta Circuit), a 14km (8.7-mile) loop that functions as a highlight reel of Swedish nature. The trail takes hikers through dark, moss-draped ancient pine forests (with trees over 400 years old), past three distinct glass-like lakes, and directly through the stark, silver skeletons of the 1999 forest fire zone. It is immaculately maintained, featuring fire pits with supplied wood, making it the significant accessible day hike.
