Getting to Catalina for Diving: Catalina Express or Dive Boat
Planning your dive adventure in Catalina Island? Getting there is easier than you think, and there are two main ways to reach the island: the Catalina Express ferry or a dive boat.
1. Catalina Express – The Fast Ferry
The Catalina Express is the most popular way to reach Catalina Island from the Southern California mainland. Departures are available from Long Beach, Dana Point, and San Pedro. The ferry ride is comfortable and scenic, offering restrooms, snacks, and panoramic ocean views. Most divers bring their gear along, so plan to arrive at least 30 minutes early for check-in. Once you arrive in Avalon or Two Harbors, you can transfer to your dive boat or explore the island.
2. Dive Boat – Direct to the Dive Sites
Some dive operators offer direct dive boat service from the mainland. These boats are fully equipped for diving, carrying tanks, weights, and all necessary gear. Dive boats take you straight to popular sites like Casino Point, Blue Caverns, and Lover’s Cove, allowing you to start your underwater adventure immediately upon arrival. The crew will help with gear, safety briefings, and boat logistics.
Tips for a Smooth Trip:
- Reserve early, especially on weekends and holidays, as spots fill quickly.
- Pack lightly—carry personal items in a small bag; dive gear is handled by the crew.
- Dress in layers, as mornings on the water can be cool.
Whether you choose the Catalina Express for a scenic ferry ride or a dive boat for direct access to dive sites, getting to Catalina is simple and sets the stage for an unforgettable underwater adventure.
