Undersea Sub Expedition

Come face-to-face with Catalina’s abundant marine life aboard Semi-Submersibles, as you cruise five feet below the surface in a spacious, climate-controlled cabin. Every passenger has their own seat and port hole and is free to roam about the cabin to enjoy other viewpoints.

Catalina's marine environment is considered one of the healthiest in the world. You’ll see an incredible array of undersea creatures, including bright orange Garibaldi, spotted calico bass, urchins, rock fish, and bat rays, just to name a few. This is more than a tour; it’s an undersea adventure.
