Cerro Castillo is a jagged rocky peak located in the Aisen Region of Chile, within the Cerro Castillo National Reserve. Castillo means castle in Spanish, and the steep basalt walls of the mountain indeed make it look like one. On its sides are a few small glaciers and lakes fed by them.
Cerro Castillo is 75km south of the city of Coyhaique along Carretera Austral. There is a small village Villa Cerro Castillo just off the road. The base of the mountain can be approached from the road in one day along Estero Parada river. An alternative is the excellent 4-day hike that starts on a spot called Las Horquetas Grandes on Carretera Austral, goes through forests, has two river crossings (no bridges), and goes over a 1,400 m mountain pass adjacent to the rock walls of Cerro Castillo. The area is remote and sees less than one hiking party per day during the season.
800m ice gully on West side, 55, alpine AD grade.
