Return Details

Returns to original departure point
Your undersea expedition starts at Green Pleasure Pier in Avalon, where you'll hop aboard the semi-submersible vessel and journey below the waterline for a look at the underwater world of Catalina Island.

Every passenger has his or her own seat and porthole, but you are also free to walk around the cabin for other viewpoints. Look for fish and other Pacific marine life as your deckhand-guide provides narration about the environment and points of interest. On the way back to the harbor, you may go up on deck to admire views of Avalon before docking.

Viator and company disappointing

We couldn’t get ferry tickets for the morning of activity. I emailed Viator 3 times and no response. Called and left 2 vm with number on ticket like instructions say. No one called back. Called again and got hung up in. So we couldn’t go after I paid. Details for activity doesn’t say you need to get a ferry way in advance. Upset I wasted that money and couldn’t go to the island.

The Undersea Experience was so much fun. It was thrilling to be cruising through the protected kelp forest of Lover's Cove with so many and varied fish all around the windows below water - right in the schools of fish feeding and looking us directly in the eye through the window periodically. We also learned a great deal about the fish, the island, and the environment through Sean's expert explanations. Highly recommend it!

Very comfortable and spacious seating. Everyone gets plenty of viewable window space. The staff were extremely friendly and the MC did a great job. They feed the fish in a few spot, so you really get to see them swarm around the boat.
