When he built the 250-acre Imanta, using mostly pink stone and wood found on location, the founder set out to create the world’s most sustainable hotel. Situated in a jungly lot next to the Sierra de Vallejo Biosphere Reserve, the resort stands far enough from the ocean to allow baby sea turtles to hatch and travel in peace, while still close enough for the azure Pacific to be within sight of (and walking distance from) the design-forward suites, villas, and treehouse. With solar-heated pools, architecture that evokes Mayan temples, and 70 percent of the staff (three for every guest) hailing from a nearby village, Imanta not only honors the land, but also its people and culture.
