Shallow Catalina Island reef dive for divers and snorkelers.
Catalina Aquarium is usually reached on a charter boat from the La Romana and Bayahibe side.
Catalina Aquarium is a boat dive on Catalina Island that stays shallow enough to work well as a second stop on a charter day. The reef is colorful and coral-rich, with sand patches that keep the profile easy to read while stingrays, nurse sharks, eagle rays, turtles, seahorses, and moray eels move through the same water. It is a friendly, relaxed site for divers and snorkelers who want an easy Caribbean reef rather than a hard drop-off.
