Finca Bellavista, Costa Rica
Finca Bellavista in Costa Rica is easily one of the most ambitious tree house developments in the world. As the story goes, founders Matt and Erica Hogan fell in love with a more than 300-acre parcel of rainforest when visiting Costa Rica in 2006. They purchased the property and got to work developing what they describe as a sustainable tree house community. Although it isn't technically a resort, the tree houses at Finca Bellavista are almost always available for rent at rates ranging from $96 per night for the rustic Cabina Colibri "jungalow" to $212 per night for the impressive El Castillo Mastate, a 1,300-square-foot octagonal tree house that is located an astounding 90 feet (27.43 meters) off the ground [source: Lawrence].
