The 1540-sq-km Parque Nacional Queulat is a wild realm of rivers winding through forests thick with ferns and southern beech. When the sun is out it's simply stunning, with steep-sided fjords flanked by creeping glaciers and 2000m volcanic peaks. The park straddles the Carretera Austral for 70km, midway between Chaitén and Coyhaique.
Created in 1983, the park is extremely popular but its far-flung location keeps it within reach of few. Visitors are challenged by the almost-constant rain (up to 4000mm per year) and impenetrable foliage. Despite its impressive size, hiking trails are few. Conaf has struggled to maintain trailhead signs, most of which are either hidden by the aggressive growth or missing.
