The Casino dive site sits just off the famous Casino building in Avalon Harbor on Santa Catalina Island, off the coast of Southern California. It is a shallow, easy shore or boat dive over rocky reef and kelp, rated a beginner site with good visibility and a maximum depth of around 22.9 metres. Octopus are a regular find here, and divers have also reported barracuda, glassfish, grouper, moray eels, lobster, nudibranchs, Napoleon wrasse, and even leopard or zebra sharks around the reef. The area is a protected no-take zone for lobster and other marine life, and kelp entanglement has been noted as a hazard, so care around the kelp holdfasts is worthwhile. The site's mild conditions and proximity to Avalon's dive shops make it one of the most frequently dived spots on the island.
