The Jules Undersea Lodge is the only underwater hotel in the United States. Located 30 feet (9 m) deep at the bottom of the Emerald Lagoo in Key Largo, Florida, guests have to scuba dive to get to their rooms. The hotel’s name comes from the novelist Jules Verne, author of 20,000 Leagues Under the Sea. Scuba certification is required for entrance as the front door is located 21 feet (6.4 m) under water.
Jules’ Undersea Lodge was formerly the La Chalupa Research Laboratory, an undersea marine lab operated off Puerto Rico in the 1970s.
While most guests at the hotel spend a night or two, on March 1, 2023, Dr. Joe Dituri, Ph.D. checked in with the intention of staying 100 days as part of Project NEPTUNE 100, an undersea mission to support marine research and conservation. After more than 75 days in the two-bedroom lodge, Dituri, a hyperbaric medicine researcher and diving explorer, who goes by the moniker “Dr. Deep Sea,” has already broken the record of 73 days for the longest time living underwater without depressurization. If all goes according to plan, Dituri will continue his underwater residency until June 9th.
