About Catalina Divers Supply
Catalina Divers Supply is the only dive and snorkel outfitter located directly at the Avalon Underwater Park, operating from the ground floor of the historic Catalina Casino Building at the north end of Crescent Avenue. Their prime location means divers and snorkellers can gear up and walk straight into one of Southern California's most famous marine preserves — no boat ride required. They carry a full inventory of rental masks, fins, snorkels, wetsuits, BCDs, regulators, and tanks for both recreational and technical diving.
The shop caters to every experience level, from first-time snorkellers exploring the kelp gardens at Casino Point to certified divers descending the underwater park's rocky walls where giant black sea bass, horn sharks, and lobster shelter among the boulders. They also maintain a second kiosk on the Green Pier in central Avalon for quick snorkel set rentals. Staff provide detailed site briefings, current conditions, and buddy-system guidance so even solo travellers can dive safely.
With decades of operation at Casino Point, Catalina Divers Supply has earned a reputation as the island's most trusted dive shop. Their gear is meticulously maintained, and the convenience of gearing up steps from the dive site — rather than hauling equipment across town — is unmatched. For visitors who want to experience Catalina's legendary underwater visibility without booking a boat charter, this is the place to start.
