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
Leann_R
, Aug 2021
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.

Excellent crew! Time and money well spent. Being a non-swimmer and unable to snorkel it was a great excursion!
