  • $75 for the above tour for six (up to a $204 value)

A replica of a US-military nuclear-operated semisubmersible, the SS Nautilus emulates the experience of diving below sea level with sound effects and bubbles outside the window. Throughout the tour, guests of all ages can wave at wild fish swimming about the hull and even feed them by pressing a button as if launching a torpedo.

Children aged 2 and younger may ride the Nautilus for free.

Catalina Adventure Tours

Catalina Adventure Tours’ aquatic guides unlock the secrets of island living during submarine and glass-bottom-boat tours or interior land excursions. Safely submersed below sea level aboard the military replica SS Nautilus, groups of up to 45 search the waters for rapidly growing ladder kelp, boisterous fish, and reflections they think are sea spirits, and those riding in glass-bottom boats start feeding frenzies among hungry schools gliding below. Alternatively, guests can spy bald eagles and buffalo during an Inside Adventure tour or gaze over cacti speckling the foreground of sweeping ocean views from the Wrigley Memorial & Botanical Gardens on the City Botanical Garden tour. Catalina Adventure Tours also runs evening missions with guides serving as curators of ocean nightlife and designated drivers for seahorse discotheques.


Everything looks high tech and clean, first class. The interior has has flat screen tv displays

    “They were extremely accomodating and offered such great tours. There was a woman in the office that helped me make some last minute changes due to a family emergency. I believe her name is Josephine - aces customer service! I would definitely contact them on my next trip to Catalina, and would highly recommend them to others.”
