World's Coolest Underwater Lodgings

Undersea hotels represent one of the newest frontiers in hospitality. From Zanzibar to Sweden, beautiful underwater properties with one-of-a-kind views have been popping up around the globe, featuring some of the most unique rooms that travelers can book. Meanwhile, closer to home, many celebrated US aquariums offer sleepovers that aren't just for kids anymore. Check out our picks for places that allow you to sleep under the sea (or at least pretend that's where you are).--Rachel B. Doyle

  • 1 The Manta Resort
    Where: Pemba Island, Tanzania
    Pemba, a verdant Indian Ocean island in the Zanzibar archipelago, has long been enticing divers with its pristine coral reefs and clear waters. Now the chic Manta Resort has taken the aquatic worship one step further, last month opening Africa’s first underwater hotel room. Submerged 13 feet underwater, the room has eight large, lit windows through which guests can gawk at a Technicolor parade of fish and cephalopods. A ladder leads to a sundeck and lounge.

  • 2 Jules' Undersea Lodge
    Where: Key Largo, FL
    The granddaddy of underwater hotels, Jules’ Undersea Lodge–a former marine lab that opened as an inn in 1986—has an unusually high bar to entry. All guests desirous of spending the night need to know how to scuba dive. There’s no other way to enter this two-bedroom retro hideout, 30 feet below the surface in a mangrove-laden lagoon. The customary underwater dinner is pizza from Papa John’s, but guests can upgrade to local lobster or filet mignon.

  • 3 Hydropolis Underwater Hotel and Resort Dubai
    Where: Dubai, UAE Where would they build the most ambitious luxury hotel under the waves? Dubai, of course. The Emirate that brought you a man-made island in the shape of a palm tree now hopes to unveil the Hydropolis Underwater Hotel, in a Hyde Park-sized complex 66 feet under the sea. Guests staying at one of the 220 suites will be greeted at the "land post" on Jumeriah beach and taken by submerged subway to the main part of the hotel. The developers say that they hope to welcome 3,500 guests a day, once they overcome "financial constrictions." Plan Your Trip: Visit Fodor’s Dubai GuidePhoto Credit: foco design
  • 4 Utter Inn
    Where: Västerås, Sweden The most rustic underwater hotel of the bunch, the tiny and adorable Utter Inn gently bobs in Sweden’s Lake Mälaren. The visible part of the hotel is designed like a typical Swedish home, with an A-frame roof, red sides and white gables. Down a 10-foot ladder there’s a cozy room with twin beds and panoramic windows to watch pike and perch swim by. With no electricity, the tranquility here is absolute.

  • 5 Poseidon Undersea Resort
    Where: Fiji Some 150,000 people have allegedly signed up to be notified once Poseidon Undersea Resort opens for business. The five-star underwater resort in Fiji was scheduled to launch in 2008, but a combination of the global recession and the difficulty of sub-aqua building have led to it still being incomplete five years later. Ambitious projections show an underwater library, golf course, and tennis court, while the website promises future guests the use of a personal submarine.

  • 6 National Aquarium
    Where: Baltimore, MD Although the U.S. only has one underwater hotel, America leads the pack when it comes to aquarium sleepovers. At the National Aquarium in Baltimore, home to over 17,000 animals, overnight visitors can choose between shark or dolphin-themed sleepovers. An underwater viewing area morphs into dramatic sleeping quarters, and guests can take nocturnal tours, watch dolphin shows, or see sharks being fed. At $115 per person including breakfast and dinner, this may be the best deal in Baltimore’s popular Inner Harbor area. Plan Your Trip: Visit Fodor’s Baltimore GuidePhoto Credit: Gian Marco Valente/
  • 7 The Georgia Aquarium
    Where: Atlanta, GA Kudos to the Georgia Aquarium, the world’s second largest, for realizing adults might want to have aquarium sleepovers too. This aquarium, home to some 100,000 sea creatures, offers the 21+ crowd a package with live jazz, cocktails, and behind-the-scenes tours. Guests can then sleep in until 10 am on mattresses plopped in front of beluga whales or a giant Pacific octopus. Plan Your Trip: Visit Fodor’s Atlanta GuidePhoto Credit: Patrick Williams Photography
  • 8 Oregon Coast Aquarium
    Where: Newport, OR Overnight guests at the Oregon Coast Aquarium get to bed down in underwater walkways along with some 5,000 species. With its 360-degree views, this exhibit has an apt nickname: the shark tubes. The itinerary for kids includes a scavenger hunt through different marine habitats, and the package also comes with two meals for $60. The program for adults is less scripted (sadly, no scavenger hunt), but can include a tour of a nearby brewery.

  • 9 uShaka Sea World
    Where: Durban, South Africa Slumber parties at this South African aquarium take place in a highly realistic replica of a wrecked 1940s steam ship outfitted with massive fish tanks. Overnight visitors to the cleverly designed uShaka Sea World can wander through four connected “shipwrecks,” where they’ll find 32 tanks boasting many species of rays, an array of incredibly poisonous reptiles, and one of the most diverse collections of sharks in the world.

  • 10 The Aquarium of the Pacific
    Where: Long Beach, CA Leave it to Southern Californians to figure out that aquariums and meditation are a perfect match. The adults-only package at the Aquarium of the Pacific involves a yoga session, fish feeding, and an informal lecture on marine life for $80. A pizza dinner and light breakfast are included, and alcohol is available (once you’re done demonstrating chakravakasana poses to sea otters.)
