Nautilus Semi-Submarine Excursion

Come face-to-face with Catalina’s abundant marine life by cruising five feet underwater in a spacious, climate-controlled cabin.

What marine life will we see? Experience underwater sights from aboard the Nautilus Semi-Submersible on Catalina Island. You may see an incredible array of undersea dwellers: bright orange garibaldi, spotted calico bass, urchins, rockfish, and bat rays, just to name a few. This is absolutely mother nature’s trip so we never know what we’re going to see.

For your safety, you should be in good health & free from motion sickness or other conditions that could be aggravated by this tour. Please note all guests must be ambulatory and able to use ramps and stairs to enter and exit the Nautilus. There are twelve stairs up and down between the dock and the seating area on board the boat.

Bring your confirmation (on your phone or tablet is great – no need to print). We will provide you with your boarding pass tickets upon check-in at the ticket booth.

Wear comfortable clothes and shoes based on the season. High heels are not recommended. Check the Catalina Island weather forecast and dress appropriately. Small bags/purses can be accommodated, but please do not bring any large bags aboard. Larger bags can be left securely at the Cabrillo Mole luggage storage or lockers. Gratuity for your deckhand or captain and fish food is not included in your ticket.
