Welcome to Jules’ Undersea Lodge!

Located in the lagoon at Key Largo Undersea Park, Jules’ is the world’s only underwater hotel where scuba diving is the only way to get to your room. In addition to overnight stays in the Lodge, the Park offers a great SCUBA training location in its Lagoon, with a depth of up to 30′ in a protected setting. Individuals can get Open Water certified here, do a Discover SCUBA Diving course, or just dive around in the lagoon.

Some of our distinguished visitors include Aerosmith’s Steve Tyler, actor Tim Allen and former Canadian Prime Minister Pierre Trudeau! We’ve been featured in several magazines and broadcast shows, too.

After you’re done with your SCUBA skills, or if you are already SCUBA certified, you can visit Jules’ Undersea Lodge for three hours or an overnight! Have lunch in the Lodge, do a three hour Mini Adventure, or sleep underwater! Distinctive PADI Specialities are available for overnight guests. Check out our video!
