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.

    Definitely a fun and unique experience! The submarine does fill up with people so definitely try and get there early so you can get a good seat. We were the last people on as a family of 8 and we were spread out all over but it worked out fine. One side has clearer windows while the other is okay, but it was super neat to see all the fish swarm around us as they know when the yellow sub comes that food will shortly follow lol!

  • Good experience.
