Fodor's Expert Review Parque Nacional Vicente Pérez Rosales

Chile's oldest national park was established in 1926. South of Parque Nacional Puyehue, this vast 2,538-square-km (980-square-mile) preserve includes the Osorno and lesser-known Puntiagudo volcanoes, as well as the deep-blue Lago Todos los Santos. The Volcán Osorno appears in your car window soon after you drive south from Osorno and doesn't disappear until shortly before your arrival in Puerto Montt. There is a visitor center opposite the Hotel Petrohué that can provide info on several hikes, such as the Rincón del Osorno trail that hugs the lake and the Saltos de Petrohué trail, which runs parallel to the river of the same name.
