I've been searching for an animal rescue/rehabilitation center in the Peruvian part of the Amazon, but really seem to find any, where it doesn't cost a fortune to volunteer. Can anybody help me find one, where it is possible to work for a month or two?
Try here: www.esperanzaverdeperu.com
its located in Ucayali province near the Brazil border.
There are low level fees to cover your food and board, but at ~local prices, you can work there for a month or two no problem.
[ Edit: Sorry, no promos please. ]
Not in Peru, but cheaper then most places I can find out there. I'll be heading here next year...
