Cerro Arenales is a heavily ice-covered volcano located in the Aysen Region of Chile, within Laguna San Rafael National Park. It towers over the southern part of the Northern Patagonian Ice Field.
The first ascent of Cerro Arenales was made in 1958 by a Japanese-Chilean expedition, headed by Professor Tanaka. In December 1963 an expedition led by Eric Shipton, crossed the NPIF heading southeast from Laguna San Rafael to Rio de la Colonia and accomplished on the way the second ascent.
