Anguilla Main Island and Cays is defined by its coral reef diving, with a site mix that ranges from shallow shore entries to deep wrecks and complex cave and canyon topography. The Shoal Bay Reef cluster anchors much of the diving, offering walls, drop-offs and seagrass beds across a wide spread of skill levels. The MV Sarah, an artificial reef wreck, draws intermediate divers to serious depth. Marine life is remarkably consistent: Nurse Shark and Green Sea Turtle are observed across most sites, alongside Queen Angelfish, French Angelfish, Spotted Moray and Whiptail Stingray. Almost all sites require boat access.

Angel Reef, Crystal Reef, Beacon and Frenchman's Reef are all beginner-friendly boat dives with shallow starting depths. La Basse Espagnole is rated advanced due to strong currents and complex cave and canyon topography, so newer divers should discuss site selection with their operator.
The overwhelming majority of sites are boat-access only, and several operators serve the region including Scuba Shack Limited, iDive 264, Vigilant Divers and Open Seas Charters Anguilla, among others.

Coral reef dives form the backbone of the region, with walls, drop-offs and shallow reef tops providing variety across many sites. La Basse Espagnole adds cave and canyon diving for advanced divers seeking more complex topography. The MV Sarah stands apart as a dedicated wreck and artificial reef, resting at considerable depth and suited to intermediate divers. Captain Turtle and Shoal Bay Reef also feature seagrass beds, which attract Green Sea Turtle.
