Yellow Semi-Submarine Tour of Catalina Island From Avalon

If you’re headed to Catalina Island and looking for a family-friendly activity that offers a glimpse into the ocean’s hidden treasures, the Yellow Semi-Submarine Tour from Avalon is worth considering. This 45-minute adventure takes you beneath the surface of Lovers’ Cove, without the need to snorkel or scuba.

Instead, you’ll stay dry inside a vessel inspired by America’s first nuclear submarine, the USS Nautilus, while marveling at marine life through clear portholes.

What makes this experience appealing is how accessible it is — particularly for families with young children or travelers who prefer not to get in the water. We’re especially fond of the friendly, knowledgeable guides and the stunning views of the island from the top deck during the return trip.

However, a potential drawback is that the tour can feel somewhat hurried at times, with some reviewers noting less-than-informative commentary and a charge for fish food that adds to the cost.

This tour suits those seeking an easy, educational, and visually engaging activity. If you’re curious about marine life or want a relaxing way to enjoy Catalina’s scenery, this semi-submarine ride provides a fun and safe option — especially if you’re traveling with kids or prefer not to snorkel.

• Flexible departure times ensure you can fit it into your Catalina itinerary.

What to Expect on the Semi-Submarine Tour

We love the way this tour balances entertainment and education in a brief but memorable outing. The semi-submarine, called the SS Nautilus, is styled after the historic USS Nautilus — a clever nod that adds a little nautical charm. Boarding at Green Pleasure Pier, you’re quickly immersed in the anticipation of a unique experience that offers close-up views of Lovers’ Cove’s marine ecosystem.

The adventure begins as you descend about six feet below the ocean surface. From there, you peer out of specially designed portholes to see schools of fish, kelp forests, and other sea creatures that inhabit this protected sanctuary. Many reviewers note the thrill of seeing fish feeding right outside the window, especially if you’ve purchased fish food (which is available for an extra charge in cash). As one guest enthusiastically shared, “Joe our guide was awesome! Funny too! Picks up at the end of the green pier and brings $20 extra cash for fish food — totally worth it.”

The semi-submarine’s windows are a key feature, giving a clear view of the underwater world. However, it’s worth noting that some reviewers mention that one side of the vessel has clearer windows than the other, which can affect your viewing experience. It’s good to arrive early to secure a seat on the side with the best visibility.

Underwater Gardens and Fish Feeding

During the tour, your guide points out various fish and undersea plants, sharing snippets of information that make the experience both fun and educational. As one reviewer exclaimed, “We saw thousands of fish,” highlighting just how vibrant the marine life can be. Some guests find the feeding activity to be a highlight — pushing a torpedo-like button to release fish food and trigger a feeding frenzy outside the portholes. This interactive element is especially popular with kids, and many report that their children’s faces lit up during this part of the tour.

While the primary focus is on observing marine life, the guides also share details about the local ecosystem, adding depth to the experience. Several reviews praise the guides’ knowledgeable and friendly demeanor, making the short trip feel personal and engaging.

The Return and the View from Above

After about 45 minutes beneath the surface, the vessel surfaces and begins the return to Avalon. This part of the ride offers a superb opportunity to take in breathtaking views of Catalina Island’s coastline from the vantage point of the top deck. Many travelers enjoy snapping photos of the rugged cliffs, colorful buildings, and bustling harbor while recounting the highlights of their underwater adventure.

The Practicalities: Timing, Costs, and Booking

The tour departs hourly from mid-morning until sunset, giving plenty of options to fit into your day. Ticket prices are quite reasonable at $53 per person, offering good value considering the unique perspective it provides — especially for those who prefer not to snorkel or dive. Keep in mind that fish food is an extra charge (around $20 cash) if you want to enhance the experience. Several reviews emphasize that feeding the fish is viewed as a must-do for maximum enjoyment, so plan accordingly if you want to include this.

Transportation to Catalina Island is not included in the ticket price. You’ll need to book a ferry, such as Catalina Express or Newport Flyer, to reach Avalon. Once on the island, the tour departs from Green Pleasure Pier, which is easily accessible and near public transportation options.

Participants are advised to arrive 15 minutes early to check in, as the boat leaves promptly. The maximum group size is 48, which helps keep the atmosphere intimate enough for personal interaction, but also means arriving early is wise during busy periods.

What the Reviews Say

The tour has earned a solid 4.3 out of 5 from nearly 500 reviews, with many guests raving about the guides’ friendliness and knowledge. One reviewer shared, “Jo and her crew were GREAT! We had the best time and saw so many fish, it was awesome.” Others appreciated the stunning views from the top deck, noting that “the harbor views on the return trip are breathtaking.”

Some guests pointed out minor downsides, like less-than-informative commentary or feeling rushed, but these are often outweighed by the fun of being so close to the marine life. A recurring theme among positive reviews was how feeding the fish added an interactive element that kids loved. Conversely, a few reviews mention a less courteous crew member, which serves as a reminder that customer service can vary.

The tour is especially popular with families, with many reviewers mentioning how the experience is perfect for children and those who don’t snorkel. Its short duration makes it easy to slot into a day of sightseeing without feeling overwhelmed.

Who Should Consider This Tour?

This semi-submarine trip is ideal for families traveling with kids, those wanting a non-swimming way to see marine life, and anyone curious about Catalina’s underwater environment. It’s perfect if you want a relaxed, informative, and visually engaging activity that doesn’t require physical exertion or special gear.

If you’re an ocean enthusiast eager for close-up views of fish and kelp, you’ll love the interactive fish feeding. On the other hand, if you’re seeking a deep-dive into marine biology or more extensive underwater exploration, you might find this tour a little light. However, for a quick, fun, and educational glimpse into Catalina’s sea life, it’s hard to beat.

The combination of friendly guides, stunning harbor views, and the chance to see a variety of fish through clear portholes makes it a memorable outing.

It’s a relaxing way to enjoy Catalina’s underwater world without getting wet or needing snorkeling gear.

This tour appeals most to families, casual ocean lovers, and travelers curious about marine life who want a straightforward, engaging, and reasonably priced activity.
