Catalina Island is a popular cruise port offering visitors plenty of activities. For those that want to learn about the underwater world located beneath the surface surrounding Avalon, a laid-back island town of 3,736 people then the Undersea Expedition Tour is a great choice.

One of the big surprises on the semi-submersible vessel was the spacious air-conditioned cabin that had large windows on both sides for prime viewing.

Expect to come face-to-face with Catalina’s abundant marine life, especially since the crew feeds the fish you will see bright orange garibaldi and spotted calico bass as well as urchins, rockfish, bat rays, and maybe even encounter a rare sighting of a turtle from the windows.

Come face-to-face with Catalina’s abundant marine life by cruising five feet under water in a spacious, climate-controlled cabin. Every passenger has their own seat and port hole plus you’re free to roam about the cabin seeking other viewpoints.
