Rancho Pacifico

Howler monkeys are your wake-up call at this certified “green,” adults-only retreat on 250 acres of dense rainforest. An adventurous spirit is a prerequisite, but roughing it is not, with comforts like private plunge pools, an open-air spa, and organic four-course dinners. The TreeHaus villas are at bird’s-eye level, 20 feet up in the forest canopy, with Jacuzzis and hammocks overlooking the Pacific. As there are just 10 rooms overall, guests and staff bond in short order, sharing tips on rainforest hikes, zip-line tours, and fishing expeditions.
