This guard will remain in place as long as the climate allows it and can be suspended by the Department of Natural Renewable Resources for security reasons (e.g., risk of avalanches).
Park rangers will be available in Puente del Inca whenever the checkpoint in Horcones is closed.
“All visitors who wish to enter the Park are required to contact them prior to their entry”
