About

Experience an Underwater Adventure

Step aboard the semi-submersible Nautilus for a unique perspective on the ocean habitat surrounding Catalina Island. This custom-built vessel gives you the chance to sit below the waterline and gaze out through large portholes as you glide past kelp forests - and possibly spot schools of colorful fish, rays and peaceful marine sanctuaries.

The Nautilus Semi-Submarine Journey

The Nautilus is inspired by the famed USS Nautilus and blends comfort with adventure. As your captain navigates along Catalina’s scenic coastline, you'll pass through protected waters crowded with aquatic life. Each guest has access to a porthole, ensuring every moment spent aboard reveals a new underwater scene.

  • Watch as brilliant orange Garibaldi and other native fish swim past

  • Observe swaying kelp forests and rocky reefs

  • Enjoy the insights of a local crew familiar with the area’s ecosystem

Interactive Features

Enhance your marine experience using the torpedo-shaped buttons at your seat, which control fish food dispensers (available separately for purchase). Feeding bursts attract hungry fish, letting you witness a flurry of activity just inches from your window.

Evening & Nocturnal Explorations

Depending on the season, select evenings offer special departures designed to highlight nocturnal sea life. Watch for nocturnal creatures emerging as the sun sets, and experience the shift in the marine environment beneath twilight waves.

Perfect for Families and Groups

This semi-submarine excursion is suitable for guests of all ages, combining fun underwater observation with educational moments. If you are traveling with family or friends, it's a stress-free and accessible way to glimpse the natural world below the surface.
