Waldorf Astoria Maldives Ithaafushi

The glass floors in the spa's treatment pavilions look straight down into the Indian Ocean, which sets the tone for this Forbes Five Star resort spread across three private islands in the Maldives. Eleven restaurants range from a treetop perch to a wine cellar cave, and the villas blur the line between indoors and the water surrounding them. The whole place is built around the premise that the ocean is the amenity.
