Sheltered Catalina reef with easy boat access.
The site is normally reached through a Catalina day-trip boat, so local routing is the practical way in.
The Aquarium is a sheltered west-side Catalina reef with a sandy bottom, coral patches, and an easy boat approach. It is usually the relaxed second stop on a Catalina day trip, with calm water and a shallow profile that works well for newer divers. Expect reef fish, rays, morays, seahorses, and other small marine life around the coral.
