Dive Site Overview
Engaging with Jules Undersea Lodge provides a distinct opportunity for recreational divers to experience life beneath the surface. This unique underwater habitat, originally constructed in the 1970s as 'La Chalupa,' has evolved beyond its initial purpose to become the world’s only facility where certified divers can actually live and work beneath the sea.
Operated within a protected lagoon at MarineLab Undersea Park, the facility functions as an active undersea research station, an exclusive hotel, and an educational attraction. Divers approach the habitat and enter through a moon pool, typically encountering the entry point at around 25 ft / 7.6 m. From here, one transitions into the dry interior rooms, where the living space is approximately 22 ft / 6.7 m.
The ability to inhabit this subsea environment allows for an immersive educational experience, often including overnight programs. Participants can earn a PADI Distinctive Specialty Aquanaut certification, deepening their connection to the marine world.
A visit here offers direct insight into ocean technology and ongoing conservation efforts, providing a tangible understanding of underwater living.

Dive Experience & Conditions
Diving conditions at Jules Undersea Lodge are largely defined by its unique lagoon environment. Access involves a shore entry directly into this protected body of water. While the dive itself remains shallow, typically around 25 ft / 7.6 m to the habitat’s exterior, conditions beneath the surface can exhibit variability. Divers should anticipate the possibility of reduced visibility, which is occasionally reported, particularly closer to the habitat’s entrance. At times, visibility has been noted to drop to only a few feet, demanding careful navigation. Silt is present on the lagoon floor and is easily disturbed, which can further diminish visual clarity during the approach and entry phases of the dive. Water temperatures, especially in winter months such as January, can be distinctly chilly, making proper thermal protection a critical consideration. Despite the overall calm and protected nature of the lagoon, these potential visibility and temperature fluctuations necessitate heightened situational awareness and strong buoyancy control.
Dive Difficulty & Safety Guidelines
Diving to Jules Undersea Lodge requires a PADI Open Water Diver certification or equivalent, but completing a PADI Scuba Refresher or PADI Discover Scuba Diving prior to your visit can be beneficial. Given the potential for reduced visibility and silt disturbance, strong buoyancy control is crucial for a smooth approach and entry. Training such as the PADI Peak Performance Buoyancy and PADI Underwater Navigator specialties will enhance your experience, helping you manage your dive in conditions that may feel confined or obscure. Always perform thorough pre-dive checks and maintain good communication with your dive buddy.
