What is a Catalina Island Scuba Diving Trip Like? Tips for Your First Adventure

A Catalina Island scuba diving trip is a rite of passage for divers in Southern California. Just a short ferry ride from Los Angeles, the island offers crystal-clear waters, vibrant kelp forests, and encounters with marine life like garibaldi, leopard sharks, and playful sea lions. With both beach and boat dives available, Catalina appeals to beginners and experienced divers alike.

Planning your trip well ensures you get the most out of your underwater adventure, from packing the right gear to choosing the right certification level. First-time divers often find that knowing what to expect, from currents to marine wildlife behavior, makes the experience more enjoyable and safer.

What Dive Experiences Can You Expect at Catalina?

Catalina offers both shore-accessible dives, like Casino Point Dive Park, and boat trips to deeper offshore sites. Beginners can enjoy shallow reefs with colorful fish, while advanced divers explore wrecks, walls, and night dives.

Visibility is often excellent, and the kelp forests provide both beauty and shelter for marine life. Divers also have the opportunity to practice navigation skills, buoyancy control, and underwater photography in a variety of conditions. These elements make Catalina one of the most versatile and rewarding dive spots in California.

Do You Need Certification for Catalina Dives?

While Try Scuba programs are available, most dives at Catalina require an Open Water Certification. At Scuba Schools of America & Swim (SSAS), students complete pool training onsite before finishing ocean dives at Catalina itself. Monthly trips give new divers a chance to earn certification while experiencing the island firsthand. 

Even certified divers benefit from guided trips, as local instructors can provide insights about seasonal conditions, marine life activity, and the safest routes between dive sites.

How Should You Prepare for a Catalina Dive Trip?

Water temperatures at Catalina typically range from the high 50s to mid-60s, so a full wetsuit, hood, and gloves are recommended. Packing a dive computer, safety marker, and defog solution makes dives safer and more enjoyable.

Traveling light is also important. Renting bulky equipment like tanks, weights, or regulators on the island can reduce the hassle of ferry travel. Divers should also plan meals, hydration, and rest between dives to maintain energy and focus underwater. Understanding these small but important details can make the difference between a good dive trip and a great one.

Budgeting for your trip includes ferry tickets, gear, food, and lodging if you’re staying overnight. Booking through a local dive shop like SSAS often simplifies logistics and ensures you’re diving with experienced guides.

What Makes Catalina Trips Unique?

Beyond the diving itself, Catalina offers a relaxed island vibe with restaurants, hiking trails, and seaside charm. Divers often combine morning dives with afternoon exploration, making it a complete getaway experience.

The combination of easy access, world-class underwater scenery, and opportunities for both learning and adventure makes Catalina a must-visit for any Southern California diver. Whether you’re traveling solo, with friends, or on a family outing, the island has experiences to suit all skill levels.
