Underwater hotel, where you need to dive to enter.
90
When dive certified guests visit Jules' Undersea Lodge in Key Largo, Florida, they discover that the name is no marketing gimmick. Just to enter the Lodge, one must actually scuba dive 21 feet beneath the surface of the sea. Entering through an opening in the bottom of the habitat, the feeling is much like discovering a secret underwater clubhouse.
Jules' Undersea Lodge started out as the La Chalupa underwater research laborator in the 1970s, and was one of the most advanced research habitats created. While special research projects are still undertaken, the running of the site now supports divers who wish to book overnight stays in either of two rooms for proposals or romantic celebrations.
The main feature of each room is the large, 106 cm (42 inch) round window that looks out into the sea. While you're looking out into the murky beyond, the fish are looking in at you. The mangrove lagoon in which Jules is located is a natural nursery area for many reef fish. Tropical angelfish, parrotfish, barracuda and snappers peek in the windows of the habitat, while anemones, sponges, oysters and feather-duster worms seem to cover every inch of this underwater world.
