Catalina Island: Yellow Semi-Submarine Cruise – A Closer Look at Undersea Wonders
Imagine gliding beneath the waves aboard a bright yellow vessel, peering out through portholes at the vibrant marine life of a protected sanctuary. This is exactly what you get with the Yellow Semi-Submarine Cruise on Catalina Island. Starting from Green Pleasure Pier in Avalon, this 45-minute adventure takes you into the depths of Lover’s Cove, a renowned marine conservation area. With the cost typically around $50 per person, it’s a short but engaging way to see the ocean’s treasures without getting wet or needing a scuba license.
We love how this tour combines educational insights with playful interactions, like feeding the fish, which adds a fun, participatory element. Plus, the vessel’s design, inspired by America’s first nuclear submarine, USS Nautilus, makes it feel both historic and high-tech. One thing to consider: the tour’s duration is brief—perfect for a quick peek, but you won’t spend hours underwater, so if you’re craving a full-day marine exploration, you might want additional activities.
This experience suits travelers with a sense of curiosity and patience, especially families and those who prefer a relaxed, low-impact way to see marine life. It’s particularly popular with kids and non-divers, but be mindful that the tour involves a transfer down 12 steep steps, and is not recommended for those with claustrophobia or certain health conditions. Overall, if you’re on Catalina Island and want a unique, close-to-nature experience that’s easy to fit into a busy schedule, this semi-submarine trip hits the right notes.

An Overview of the Tour Experience
Starting at Green Pleasure Pier in Avalon, the tour sets off with the familiar sight of the bright yellow Nautilus, a semi-submarine custom-built to mimic the historic USS Nautilus. The vessel is designed for viewing, with large portholes allowing you to see marine life from a comfortable, dry environment. The 45-minute ride takes you into Lover’s Cove, a marine conservation area where the sea teems with fish, kelp forests, and other undersea creatures.
The ride is led by a knowledgeable crew and often features stories about the local marine environment. The experience is both educational and entertaining, making it ideal for families, nature lovers, and anyone curious about ocean life. The vessel’s design offers a spacious interior, and most travelers appreciate the ease of getting on and off the boat, with the only caveat being the steep steps required to access the seating area.
What Makes This Tour Special
One of the standout features is the ability to see marine wildlife up close through the portholes. Many reviews highlight how fish swim right past the windows, giving a true sense of being submerged in their habitat. Joan from the U.S. mentioned, “It was great fun! We saw tons of fish. The fish were up close and personal,” which captures this well.
Another highlight is the fish feeding activity. For a small extra fee, you can launch fish food torpedoes right from your seat, sparking feeding frenzies just outside your window. Melissa appreciated this, calling it a “wonderful experience” and noting how the guide was fantastic at keeping everyone entertained. However, some travelers, like Farzad, expressed mild disappointment about the additional cost for feeding, feeling it was a bit unfair to pay extra after the ticket price.
The Itinerary and Marine Encounters
The tour primarily involves a single route through Lover’s Cove, where the vessel hovers over coral beds and kelp forests. You’ll see a variety of fish—garibaldi, bass, and other species—though some reviews note that the number and variety of fish can vary depending on the day. For example, Katherine shared her experience, saying, “The variety of fish was not what I had hoped.”
The vessel’s design allows for excellent viewing, especially when it is calm. During busy days or rough weather, the experience might be less clear, and some reviews mention windows that could be cleaner for better visibility. Overall, most travelers felt they got a good view of natural habitats and appreciated the opportunity to observe marine life in its habitat, without the need for snorkeling or scuba gear.
More Great Tours NearbyGuides and Narration
One element that repeatedly stands out in reviews is the quality of the guides and crew. Melissa praised her guide’s fantastic personality, and Chuong appreciated Jill’s singing and humor. These personal touches make the trip more memorable. The crew also shares educational insights about kelp forests and the animals encountered, which adds value for curious travelers wanting to learn more about this delicate ecosystem.
Practical Details and Considerations
While the tour is a highlight, it’s important to consider logistics. Transportation to Catalina Island by ferry is not included, so plan for an additional cost and time. The meeting point is at Green Pleasure Pier, with precise coordinates provided. The tour departs at scheduled times, and it’s wise to arrive a bit early to ensure smooth boarding.
The steps down to the vessel may be challenging for some, and the tour is not recommended for those with claustrophobia, high blood pressure, or motion sickness. Children between 3 and 11, as well as infants, must be accompanied by an adult. Infants under 2 require a ticket, though most reviews indicate children love the experience.
Weather conditions also influence schedules; tours can be canceled or delayed due to bad weather, so flexibility is key. If you need to cancel, you can do so up to 24 hours in advance for a full refund or a voucher valid for a year.
The Cost and Value
At roughly $50 per person, the price is reasonable for a 45-minute immersive experience. It offers a unique perspective that’s hard to match with other activities on Catalina. The educational aspect and the chance to feed fish add to the overall value, especially for families or those seeking a gentle introduction to marine habitats.
However, some reviews suggest that the experience might be somewhat limited in scope—primarily a window into a small section of the ocean—so if you’re expecting a prolonged underwater adventure, this might not fully satisfy. Still, many travelers find it well worth the price, especially when combined with other island activities.
Who Will Love This Tour?

This cruise suits families with children, non-swimmers, and anyone wanting a low-impact, close-up view of Catalina’s marine life. It’s ideal if you’re short on time but want a memorable experience. Nature lovers and those interested in marine conservation will appreciate the educational insights, while kids will love the fish feeding and vibrant underwater scenes.
It’s less suitable for adventurers seeking snorkeling or scuba diving or travelers with health concerns that make steep steps or confined spaces problematic. Also, if you’re looking for a high-adrenaline activity or extensive underwater exploration, this tour may feel too brief.
