World's Best Treehouse Hotels

Why It’s Unique: Located in southern India on a private 400-acre estate complete with a working coffee and vanilla plantation, in the Kerala rainforest, the resort has a main lodge with eight well-appointed rooms. The 500-square-foot treehouse, built from coffee wood and equipped with a king-size bed, has a full bath, veranda, and the trunk of a flowering Royal Poinciana growing through the bedroom.

Access: Ascending stairs, rope bridge, and “water lift.”

What to Do: Relax by the pool, try a traditional ayurvedic massage, or take a tour of the working coffee and vanilla plantation.
