About this site
Jules Undersea Lodge sits in Emerald Lagoon, a mangrove-lined lagoon in Key Largo, Florida, part of the Florida Keys. The site is a former research habitat converted into an underwater lodge, resting in calm, enclosed water rather than open reef or ocean. It is used both for novelty overnight stays and for confined-water training dives in the sheltered lagoon. Visibility is limited compared to offshore Keys sites since it is a lagoon rather than a coral environment. It is not known for marine life encounters but rather for the experience of entering a habitat structure underwater.
