1 Best Sight in Parque Nacional Puyehue, The Lake District

Volcán Puyehue

Truly adventurous types attempt the five-hour hike to the summit of 2,240-meter (7,350-foot) Volcán Puyehue. As with most climbs in this region, CONAF rangers insist on ample documentation of experience before allowing you to set out. Access to the 1,070-square-km (413-square-mile) park is easy; head east from Osorno on the highway leading to Argentina.
