Catalina Island Day Trip with Undersea Sub Expedition
This comprehensive day trip takes you from Los Angeles to Catalina Island for an underwater adventure that shows off the Pacific's marine life without getting wet. You'll travel by ferry to the island, then board a climate-controlled semi-submersible vessel that descends 5-10 feet below the surface. Through large viewing windows, you'll see garibaldi fish, kelp bass, sea stars, sea urchins, and dense kelp forests as expert guides provide commentary about the underwater ecosystem.
The semi-submarine moves slowly along Catalina's coastline for 40 minutes, giving you extended viewing time as marine life swims past your window. Common sightings include bat rays, rockfish, and seasonal visitors like sea lions. The vessel's feeding activities outside the windows attract even more fish for close-up photography opportunities. You can upgrade your experience with the optional Discover Avalon tour, which covers 7.5 miles of the island's historic architecture and scenic viewpoints.
What is Included
- Hotel pickup and drop-off from selected hotels
- Roundtrip Catalina Express ferry ticket
- 40-minute semi-submersible vessel tour
- Optional 40-minute Avalon tour
Good to Know
The total experience lasts a full day with ferry travel time included. You'll need to arrive early for hotel pickup if you've selected this option. The semi-submarine tour runs approximately 45 minutes and is suitable for all ages, including children who typically love the educational underwater experience. The vessel is not wheelchair accessible, and you'll want to bring a camera to capture both undersea sights and Avalon's waterfront.
No swimming ability is required as you stay completely dry inside the enclosed submarine cabin. If you have severe claustrophobia, consider this before booking, though most passengers find the well-lit cabin with large viewing windows comfortable. Food and drinks are not included, but you'll have free time in Avalon for dining and shopping. ID may be required for ticket collection, and your booking confirmation will include the scheduled return ferry departure time.
If you're looking for more ways to explore Los Angeles from the water, consider the Newport Beach whale watching cruise or venture inland with a Hollywood celebrity homes tour for a complete Southern California experience.
