Cerro Catedral is a mountain located 19 kilometres (12 mi) from San Carlos de Bariloche, and inside the Nahuel Huapí National Park, Patagonia, Argentina.
The mountain holds one of the biggest ski centers in South America, with a skiable area of 2 km2 (0.77 sq mi), over 100 km (62 mi) of ski runs, and a lift capacity of 22,200 skiers per hour. It is also very popular due to the magnificent view of the Nahuel Huapi lake. There are also a number of hotels and hostels at the foot of the mountain, and a summer hikers' hut called Refugio Lynch on one of the tops of the mountain.
During the summer, the Refugio Frey and a camping accommodate trekkers and rock climbers next to Tonček lagoon, near the Torre Principal; Catedral's highest point.
