Imagine cruising just beneath the ocean’s surface in a bright yellow vessel that looks like a science-fiction submarine — but with a friendly, accessible vibe. That’s exactly what you get with the Yellow Semi-Submarine Cruise on Catalina Island, offered by Catalina Adventure Tours. For just $53 per person, this 45-minute adventure takes you into a protected marine sanctuary, where you can see an abundance of marine life up close without getting wet. Starting at Green Pleasure Pier in Avalon, you’ll hop aboard the Nautilus, a custom-built semi-submarine inspired by the USS Nautilus, the first nuclear-powered submarine.
What makes this tour particularly appealing is the chance to see marine wildlife from your own personal explorer’s seat while cruising through kelp forests and vibrant ocean habitats. The second thing we love is the interactive element: you can feed the fish right outside your porthole with specially designed torpedoes (at an extra charge), which often ignites impressive feeding frenzies.
A potential consideration is that the ferry ride to Avalon is not included**, so you’ll need to plan transportation separately. This tour suits travelers who appreciate short, engaging outings with an educational twist, especially those who enjoy marine life and want a family-friendly activity that’s both fun and informative. It’s perfect for curious kids, nature lovers, and anyone looking for a unique perspective on Catalina’s underwater environments.

A Deep Dive into the Experience

The Yellow Semi-Submarine Cruise begins at the Green Pleasure Pier in Avalon, Catalina Island. Since transportation by ferry isn’t included in the ticket price, most travelers will need to plan a separate boat ride from the mainland—whether from Los Angeles, Long Beach, or other departure points. Once you arrive in Avalon, the meeting spot is straightforward, and the check-in process seems smooth, with some reviews noting the importance of printed tickets even if you buy mobile ones.
The vessel itself is a marvel of design — bright yellow, reminiscent of a cartoon submarine, and inspired by one of America’s most famous submarines. As you settle into your seat, you’ll notice the large portholes designed to allow clear views of the underwater world. The cruise lasts about 45 minutes, a duration that packs enough time to see several marine habitats without feeling rushed.
The crew and guides are key to making this tour worthwhile. Multiple reviews mention guides like Jill and Melissa, highlighting their enthusiasm, knowledge, and ability to entertain. They point out the different fish, explain kelp forest ecosystems, and answer questions, making the experience genuinely educational. One review even praised a guide’s “spunky personality” and songs, showing that a friendly, personable guide enhances the trip.
The underwater scenery is a highlight. You’ll glide beneath the surface, observing fish swimming alongside the vessel. Many reviews mention the density of fish and kelp—more than some expected—making you feel as though you’re peering into a bustling underwater city. The fish feeding feature is especially popular; at an additional cost, you can launch food torpedoes outside your porthole, which often triggers a lively feeding frenzy. This simple act adds an extra layer of fun, especially for kids, with one reviewer noting that “kids loved feeding fish.”
The educational aspect is woven naturally into the tour. Guides share insights about marine conservation, kelp forest importance, and local fish species, making it ideal for those interested in marine ecology. The tour’s setting in Lover’s Cove — a protected marine area — assures you’re viewing a healthy, well-preserved ecosystem.
While the 45-minute duration is perfect for a quick getaway, it’s worth noting that the ferry ride to Avalon isn’t included in your ticket price. If you’re coming from Los Angeles or nearby, you’ll need to factor in the cost and time of your boat trip, which can add to the adventure’s overall expense. Also, the tour involves walking down about 12 steep steps onto the vessel, so those with mobility issues should consider this.
