One&Only Mandarina
El Monteón, Mexico
One&Only Mandarina occupies 80 acres of coastal rainforest above the Pacific in Riviera Nayarit, with a swimmable beach below. Its 105 standalone treehouses and villas are spread through the canopy and along the cliffs; separately offered private homes add another way to stay. Each treehouse and villa has a private plunge pool, though views vary between rainforest and ocean. Days can move from the beach to rainforest trails, while Carao’s cliffside dining room looks out toward the coast.
