Water Activities on Catalina Island

One of Southern California's Best Destinations for Things To Do On the Water

Twenty-two miles off the Southern California coast, Catalina Island offers some of the most spectacular water activities in the Pacific. The island's protected coves, crystal-clear depths, and thriving marine ecosystems make the sea here less of a backdrop and more of the main event. Whether you're planning a day trip or an overnight stay, water activities on Catalina Island deliver experiences you simply can't find anywhere else in Southern California.

Snorkeling and Scuba Diving on Catalina Island

Beneath the surface, Catalina Island's marine life is extraordinary. Kelp forests sway in the current, bright orange garibaldi, California's official state marine fish, dart through the rocks, and sea lions cruise the coves with casual curiosity. Catalina Island scuba diving has drawn enthusiasts from around the world for decades, with sites ranging from beginner-friendly coves to advanced open-water dives. Catalina Island snorkeling at Lover's Cove puts you face-to-face with marine life in shallow, calm water that's accessible to almost anyone, no experience necessary.

For something truly one of a kind, Catalina Island Mermaids offers mermaid classes, underwater photoshoots, and SCUBA experiences that turn a day in the water into something genuinely magical, for kids and adults alike.

Prefer to stay completely dry? Catalina Island glass-bottom boat tours and semi-submersible undersea expeditions deliver the same sense of wonder without getting your feet wet. You'll cruise directly over the kelp gardens and come away with a genuine appreciation for what lives beneath Avalon Harbor.

Kayaking, Paddleboarding, and More on the Water in Avalon

On the surface, water activities on Catalina Island are just as compelling. Catalina Island kayaking and paddleboarding through calm coves let you explore the coastline at your own pace, both are beginner-friendly and available for rent right in Avalon. Rent a boat and discover hidden coves independently, or let someone else do the navigating on a sailing charter around the island.

Thrill-seekers won't want to miss Catalina Island parasailing, which lifts you up to 800 feet above Avalon Harbor — the view of the Casino, the coastline, and the Pacific stretching endlessly in every direction is something you won't forget. Catalina Island jet ski rentals put the coastline in reach on your own terms, while Catalina Island sport fishing charters offer a classic experience that's been drawing anglers to these waters for well over a century.
