Jules’ Undersea Lodge

Key Largo, Florida

In one of the world’s most popular dive locations, the Key Largo undersea park is a great PADI dive resort. It offers a 30-foot depth dive, an anchor, a natural nursery, mangrove and marine life in a small secluded area. Operating since 1986, the site has continued to share the experience of diving in Key Largo year-round.

Perhaps you have built up your confidence by snorkelling in Key West and would like to try your hand at scuba diving in a safe environment. Jules’ Underwater Lodge is located in a lagoon and is the ideal location to learn to dive.

Description

While overwater villas are a growing trend, Jules’ Undersea Lodge was the first underwater hotel and inspired many divers and non-divers to embrace this unique accommodation style. Snorkel or dive to the natural nursery area during a guided tour around Jules’ Lagoon, where you’ll see barracuda, blue tangs, eels, manatee, sea horses, and marine life.

The marine life is enhanced by the presence of the underwater lodge. It acts as an artificial reef while the airflow adds oxygen to the entire body of water. Entering the undersea world will give you a view of the oysters, sponges, anemones, and feather duster worms.

Location

The dive site is on Shoreland Drive in Key Largo and is bordered by the Largo Sound. Arrange an airport shuttle or start a self-drive tour along the Overseas Highway from Key West or travel from Miami to Key Largo.

Key Largo’s most famous dive visits the USS Spiegel Grove shipwreck located five nautical miles offshore. If you and your family feel more comfortable above the water, you can peek at the coral reefs and fishes during a glass-bottom boat adventure.

Style and Character

The underwater hotel was formerly the La Chalupa Research Laboratory used in the ’70s to explore the continental shelf off of the coast of Puerto Rico.

The sense of history is inescapable when spending time in this underwater habitat. While the lodge features comfortable and futuristic decor, it doesn’t detract from its authenticity as the first underwater suite.

The lodge was named in honour of Jules Verne, the author of ‘Twenty Thousand Leagues Under the Sea.’ Watch a film in the evening or simply peek through the large round window found in each room.
