Casino Point Dive Park

Casino Point Dive Park on Santa Catalina Island, California, stands as one of America's most iconic and beloved coastal dive parks—a designated underwater preserve at the base of Avalon's famous casino building where the Channel Islands' extraordinary marine biodiversity is accessible to shore-diving divers without boat support, in conditions that have made it one of the most-dived and most-photographed dive sites on the American Pacific Coast. Located 26 miles off the Los Angeles coast, Catalina Island rises from the Southern California Bight with its own distinctive ecosystem shaped by the convergence of cool California Current water and the warmer southern California influence, creating marine communities of exceptional diversity and visual richness. The Casino Point site was designated as an underwater preserve in 1965, making it one of the earliest marine protected areas on the Pacific Coast. This protection has allowed fish populations to develop in the park's limits that respond to dive park conditions—fish that have been non-threateningly observed by divers for decades develop the habituation that allows extended close encounters. The giant black sea bass that occasionally appear at Casino Point—one of the Pacific's largest bony fish, capable of reaching 500 pounds and protected since 1982—represent the ultimate reward of this long-term protection, their massive, dark forms hovering with deliberate calm near the park's rocky structure. The kelp forest at Casino Point is one of the site's defining visual features—the giant kelp that forms the golden canopy above the rocky reef creates the three-dimensional diving environment that makes California kelp forest diving so compelling. Looking upward from the reef through the stipes of giant kelp toward the dappled surface light above is an experience with a cathedral quality that the world's few kelp forest dive environments provide and that no coral reef or freshwater site can replicate. California sheephead, garibaldi—the brilliant orange fish that is California's state marine fish and whose vivid color stops divers short—and the various rockfish that inhabit the kelp provide a fish community of high quality and photogenic diversity. The dive park's accessibility from the Avalon ferry terminal makes it one of the most easily reached world-class marine dive sites in the United States. A ferry from Long Beach or San Pedro delivers divers to Avalon, and Casino Point is a short walk from the ferry terminal—no boat charter, no remote access, no significant logistics beyond the ferry schedule and air fill at the nearby dive shop. This accessibility makes Casino Point one of the most egalitarian exceptional dive sites in the country, available to any certified diver who can make the ferry crossing. Night diving at Casino Point has its own dedicated following, as the site's protected status and the predictability of its marine community makes it one of the best night diving destinations on the Pacific Coast. The bioluminescent plankton that sometimes illuminates the water with ghostly blue light, the octopus and moray eels that emerge to hunt in darkness, and the transformation of familiar daytime species into their nocturnal behavior patterns collectively make Casino Point nights a dive experience distinct from anything available during daylight hours.
