Explore the Catalina Island's amazing undersea gardens by venturing on an exploratory mission aboard the semi-submersible SS Nautilus. Designed after the USS Nautilus, America's first nuclear powered submarine, this 45-minute 6-feet underwater journey departs from the Green Pier and will cruise to a marine preserved sanctuary known as the Lovers' Cove. Equipped with torpedo buttons, adventurers can create a feeding frenzy right from their viewing porthole for an additional charge. On the way back to the marina, enjoy breathtaking harbor views on the top deck of the submarine. Weather permitting, undersea garden tours depart hourly year round from mid-morning until an hour before sunset. **we highly suggest you secure transportation to Catalina island prior to booking tour to confirm you can get to the tour as the boat to the island sells out quickly. Catalina Express or Newport Flyer for your transportation needs.
