Curi-Cancha is a beautiful wildlife refuge, and we were lucky to see over 40 species of birds while touring with our guide Esteban (see his Tripadvisor page) over 4 hours. The trails are very well maintained, and numbers of visitors are limited so there are no crowds. The terrain varies from fields to secondary forest to old growth, and although it is hilly, it was not too difficult for me to walk even though I have a bad back. One area contains multiple hummingbird feeders, and you can be very close to several different species of these beautiful hummers. Curi-Cancha is definitely a go-to place for birding in the Monteverde area.
