How old is the oldest underwater hotel?

The first underwater hotel ever created is located right in the United States. Jules' Undersea Lodge, located in Key Largo, Florida, opened in 1986, according to Guinness World Records, and before it was a hotel it was an underwater laboratory.



The world's oldest underwater hotel is Jules' Undersea Lodge in Key Largo, Florida, which is 40 years old as of 2026. Originally opened in 1986, it was converted from the La Chalupa Research Laboratory, a high-tech underwater habitat used for marine biology in the 1970s. To enter the hotel, guests must scuba dive 30 feet down to the "moon pool" entrance. In 2026, it remains a premier, high-value "bucket list" experience, offering a unique "retro-future" vibe. While newer, more luxurious underwater suites have opened in the Maldives and Dubai, Jules' holds the high-quality title of the pioneer, providing a "gold-standard" immersive experience where you can watch manatees and tropical fish swim past your bedroom porthole. It’s a 40-year-old testament to human ingenuity and the enduring allure of living beneath the waves, making it a high-value destination for adventurous travelers and scuba enthusiasts alike.
