We haven't seen the maps for Termas de Chillan but we assume you can pick one up in Santiago.
Unfortunately, there is no guidebook for backcountry skiing in Chile. There is a useful, if dated, guidebook to the ski hills of Chile which has descriptions of the best lift accessible backcountry routes. It is called the South American Ski Guide by Chris Lizza. It is out of print but expensive second hand copies are available on Amazon. |
