Los Angeles: Semi-Submarine Excursion from Catalina Island

About this experience

Los Angeles Semi-Submarine Excursion from Catalina Island The Nautilus semi-submarine offers a unique underwater viewing experience off Catalina Island's coast. You'll sit 5-10 feet below the surface in a climate-controlled cabin, watching marine life through large portholes as you cruise through kelp forests and protected waters around Avalon. During the 45-minute guided excursion, you'll spot bright orange garibaldi fish, kelp bass, sea stars, and sea urchins swimming past your window. The vessel's design keeps you completely dry whilst providing clear views of the rocky ocean floor and swaying kelp forests. Fish food dispensers can be purchased onboard to attract schools of fish right up to your porthole. Evening departures are available seasonally, giving you the chance to observe nocturnal marine creatures as they emerge at twilight. The professional crew shares insights about Catalina's marine ecosystem throughout the cruise.
