Yellow Semi-Submarine Tour of Catalina Island From Avalon
Overview
Available languages
45 minutes
Mobile ticket
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.

5.00The best experience! We had a great time. I traveled with my spouse and our 10 year old daughter and we all loved it. Its a fun not to miss activity for both adults and children. We felt so upclose to marine life and the captain did a wonderful job narrating about the species of fish. From the moment we got on board to the moment we arrived back from sea we saw tons of fish! We were seated comfortably with big windows so got to see plenty!! Captain Brad was wonderful!
Excited, excellent...
