Description

Come aboard Catalina Island's newest semi-submarine, the SS Nautilus, and enjoy a deep sea adventure 1,000 leagues beyond your imagination. The main attraction of this unique vessel allows six feet underwater viewing while staying dry so eager seafarers can get up close and face-to-face with schools of fish anticipating treats fired away from custom designed fish food torpedo buttons. Designed after America's first nuclear powered submarine, the USS Nautilus, the 45-minute journey is the destination itself as our captain and his crew ventures out on an exploratory mission to the undersea gardens of Avalon Bay.

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.

So much fun!

Really fun and unique experience that we loved, as well as our 3 year old. We paid the extra $20 cash for the fish food torpedos, which was really fun, if not a little expensive. Would recommend!

Mediocre

Guy was irritable but calmed down and gave the tour reasonably well with good info , only saw perch fish …nothing else although he said to keep eye peeled for all possible ocean creatures but none other than perch were observed

we were on a cruise that stopped at Catalina Island. We booked this tour because kids were interested in seeing some marine animals. besides the ticket to the submarine ride, if you wish to feed the fish from inside, you will need to pay extra. we thought the submarine ride was just an ok..... probably wouldn't do it again.

Great Tour

Great tour, the large underwater viewing windows gave us a close look at colorful fish, kept forests, and marine life without getting wet. Friendly crew shared interesting facts throughout the trip. Definitely worth adding to your trip.
