Tired of the typical beach resort? Try something a little more natural with a stay at Finca Bellavista. Located in the mountainous South Pacific coastal region of Costa Rica, this sustainable treehouse community has seven unique treehomes available, some of which are accessible via rope suspension bridges. Other unique features include ziplines through the rainforest, hiking trails, and reasonably close access to the ocean and nearby towns. And don't worry if you don't feel like leaving — they'll be more than happy to sell you a parcel, help you build your own treehouse, and welcome you into the community.
