I might fly to Peru for a couple weeks in December and was thinking about attempting an 18,000'+ peak while I'm there. I haven't climbed anything above 14,400' and just have some basic snow skills from Winter 14ers in Colorado (no experience with glaciers/crevasses). I'd really appreciate any recommendations as to peaks I could attempt in the Peruvian Andes. Is the weather manageable in December? Thanks for any information.
