Semi-Submarine Tour of Catalina Island

A tour to discover the underwater world of Avalon Bay while staying dry

4.1 · Very good(135 reviews)

On this 45-minute tour, you’ll hop on Catalina Island’s popular semi-submarine SS Nautilus, which is named after America’s first nuclear-powered submarine USS Nautilus. Your journey will begin from the Green Pier as the semi-submarine departs and heads to the Lover’s Cove in Avalon Bay, which is a marine preserved sanctuary.

You’ll get to be up close with a variety of fish while staying dry as the vessel allows six feet underwater viewing. You can choose to feed the fish from inside the vessel through its custom-designed fish food torpedo buttons. On your way back to the marina, you can relax on the top deck of the submarine to see unrestricted harbour views.
