Conrad Maldives Rangali Island—Rangali Island, The Maldives
This island resort is famous for its Ithaa Undersea Restaurant, the world’s first all-glass dining establishment completely submerged underwater. It’s also one of the only locations in the world where you shouldn’t be afraid of sharks staring at you. Above ground, Conrad Maldives Rangali Island provides spectacular views of the Indian Ocean. Stop for a unique massage in the Over Water Spa, tiki hut-style rooms with glass floors that allow you to watch colorful fish swim below you during your treatment. These one-of-a-kind restaurants around the world will blow you away.
The Manta Resort—Pemba Island, off the coast of Tanzania
The most exciting part of this underwater hotel isn’t even attached to the hotel. It’s called the Underwater Room, your own private floating island where you can sleep under the sea or under the stars. A boat takes you from the mainland to your little paradise. The landing deck with a lounge area and bathroom is at sea level. Climb up the ladder to sunbathe or stargaze on the rooftop, or head below deck to your bedroom for a nearly 360-degree view of underwater life. Prepare to see exotic fish, squid, and even an octopus during your stay at the Underwater Room. Check out more stunning vacation spots that let you sleep outside and be one with nature.
Atlantis The Palm—Dubai, United Arab Emirates
Some island vacations don’t require a passport, namely these islands right in the U.S. Atlantis The Palm is not one of those islands, but its picturesque views of the Arabian Sea are well worth the trip. It was the first resort built on an island and is located on the world’s largest man-made island, Palm Jumeirah, which actually looks like a palm tree. Atlantis The Palm also offers floor-to-ceiling views of the sea in its underwater suites, even in the bathrooms. Guests can dine at not one, but two underwater restaurants, Poseidon Café and Ossiano. The latter is renowned for its seafood, though it may feel disconcerting to eat the same creatures swimming mere feet away from your plate.
