I´m further south FS and it´s over the Atlantic coast. If you come close just come by. All DB bros and sis have a place to stay where I live.
Peru is a beautiful place to go all year long. If you plan to go to Machu Pichu they say it´s better to visit between April and October. It´s the dry season so there´s little rain. You can climb your mountain then. If you go there in summer (J, Feb, M) you´ll find some rain and some occasional flooding (mainly in the mountains and the Titicaca lake).
