Aquarium Gros Ilets is a boat-accessed shallow site just off Gustavia harbor in Saint Barthélemy. The water stays calm, the terrain is easy to read, and the site feels like a natural aquarium for beginner divers and snorkelers alike. It starts very shallow and gradually opens into a modest reef scene with pretty coral structure, lots of reef fish, and frequent lobster sightings. This is a relaxed, close-to-harbor dive rather than a site for depth or strong conditions.
