Undersea Expedition: Catalina Island Tour

Descend 5 feet beneath the surface of one of California’s most extraordinary marine ecosystems, all from the comfort of your own personal porthole in our semi-submersible.

Gaze at Giant Kelp forests rising from the ocean floor as large schools of calico bass, bright orange garibaldi, and the occasional diving cormorant or seal pass by to say hello. The top of the boat always remains above the surface in case you need to head upstairs for some fresh air!

Our captain also offers a harbor cruise on the ride back to the dock so you can look for dolphins and enjoy the ocean breeze while taking in the stunning views of Avalon.
