Yellow Semi-Submarine Tour of Catalina Island From Avalon

See the sea without getting wet. This 45-minute ride aboard the yellow semi-submersible SS Nautilus gives you a close look at fish, kelp, and Avalon Bay from six feet below the surface. I like the family-friendly format, especially for children too young to snorkel, and I like the easy schedule, with departures running from mid-morning toward sunset. The extra charge for fish food is the main catch, and you need cash if you want to bring the fish right to your window.

The tour is simple, short, and good fun rather than a major marine expedition. I also like the return ride on the open top deck, where you trade the porthole for harbor views and fresh air. Just arrive 15 minutes early, since the boat leaves promptly and there are no refunds for arriving late.

Key points before you book

• Six feet below the surface: You stay dry while watching fish through individual viewing portholes at Lovers’ Cove.
• The fish-food torpedo: For an extra cash payment, you can press a button that releases food near your porthole.
• A strong pick for children: Kids often love the submarine theme, the close fish views, and the torpedo buttons.
• Only 45 minutes: The ride fits neatly into a day of exploring Avalon, but it is not a full coastal cruise.
• Top-deck views on the way back: After the underwater portion, you can see Avalon Harbor and Catalina from above.
• Plan around the ferry: The ticket covers the tour only. You must arrange your own ride to Catalina Island.

What this Avalon submarine ride is really like

The SS Nautilus is not a fully enclosed ocean-going submarine. It is a semi-submersible boat, designed with the look of the USS Nautilus, the first nuclear-powered submarine in the United States. The lower cabin sits below the surface while the upper deck remains open to the air.

That design makes the trip easy for most people. You do not need swimming skills, snorkeling gear, or a tolerance for getting splashed. You simply sit at a viewing port, listen to the English-speaking guide, and watch the sea pass at eye level.

The underwater portion reaches about six feet below the surface at Lovers’ Cove. That is shallow enough for sunlight to reach the kelp and fish, which helps create the bright, aquarium-like view that makes this activity appealing. You are not exploring a remote reef or traveling far offshore. You are getting a close, convenient look at a protected marine area just outside Avalon.

I see this as an introduction to Catalina’s sea life. It gives you a taste of what is below the bay without taking half a day or asking you to handle equipment. If you already snorkel or scuba dive, the experience may feel modest. If you want a dry, low-effort way to see fish up close, it makes much more sense.

Boarding at Green Pleasure Pier

The tour begins at the Green Pleasure Pier in Avalon. Your ticket is held at the will-call window, so you collect it on the day of the ride. You should arrive at least 15 minutes before departure for check-in and boarding.

This timing matters because the boat leaves on schedule. Catalina trips often involve ferry timetables, and the submarine operator does not wait for late arrivals. Build in enough time to walk from your ferry arrival point to the pier, find the will-call window, and board without rushing.

The boat can carry up to 48 people. That is a moderate-sized group, not a private outing. If you are traveling with a large family or group, arrive early so you have a better chance of sitting together. One family of eight found that arriving late left them spread around the boat.

Once aboard, the crew gives the basic orientation and guides you toward the lower viewing area. The cabin is the heart of the tour. Each passenger looks through a porthole, so your view is personal rather than one broad window shared by everyone.

Lovers’ Cove and the underwater gardens

The boat travels from the pier toward Lovers’ Cove, a marine sanctuary near Avalon. This is the main attraction, and the boat pauses in the area so you can watch the fish gather around the windows.

The setting has the feel of a natural aquarium. You may see bright orange garibaldi, opaleye, grouper, and other local fish. One outing produced views of a manta ray, while other reports describe seeing thousands of fish around the boat. The exact show depends on the conditions and the creatures nearby, so I would treat the manta ray as a lucky sighting rather than a promise.

Kelp is another part of the scene. The undersea gardens are not just a backdrop for fish. They show you one of Catalina’s coastal habitats, with plant life moving in the water and fish using it for shelter. The guide may point out what you are seeing, but the amount of explanation can vary from one departure to the next.

That variation is worth knowing. Some crew members have been praised for making the ride funny, warm, and informative. Jo, Joe, Brad, and Dave are among the names singled out for friendly service on past departures, and one newer guide impressed a mother and daughter with his calm, kind manner after only two days on the job. At least one report described a less patient crew member and too little information about the fish.

So, I would book this for the sights first and the narration second. When the guide is engaged, the experience becomes much better. When the commentary is thin, the fish still provide the main entertainment, but you may wish for more detail.

The fish-food torpedo costs extra

The most talked-about feature is the fish-food system. From your seat, you can press a torpedo-style button to release food outside the submarine. The fish then gather near the portholes, often giving children an almost nose-to-nose view.

The food is not included in the $53 ticket. It costs extra, is cash only, and the practical advice is to bring about $20 if you want the feeding option. You should also bring a little extra for a tip if you feel the crew has done a good job.

This add-on changes the experience. Without it, you watch fish moving naturally around the boat. With it, you create a concentrated burst of activity right outside your window. Families with younger children often find the button more exciting than the submarine ride itself.

Use the food carefully. The system makes three stops, and one passenger used the entire supply at the first stop because the arrangement was not explained clearly at the beginning. Ask the crew how much food you receive and when to use it before pressing the button repeatedly.

I understand why the extra charge bothers some people. The activity already costs $53, so the feeding option can feel like a surprise fee if you arrive unaware. Still, it is optional. If your budget is tight, you can skip it and watch the fish without paying more. If you are bringing children, I would decide in advance if the extra cost is worth the likely excitement.

The return ride gives you a second view of Avalon

After the underwater portion, the boat comes back to the surface. This is when you can head to the top deck and enjoy the ride back toward Avalon.

The change of viewpoint is welcome. Below deck, you focus on portholes, fish, and kelp. Above deck, you get open harbor views and a better sense of Catalina’s hills and shoreline. The top deck also gives you a chance to stretch and get fresh air before returning to the pier.

The trip ends where it begins, at the Green Pleasure Pier. The full ride lasts about 45 minutes, so it leaves plenty of time for lunch, a walk through Avalon, or another activity. It also works well as a filler between ferry arrival and a later departure, provided you allow enough time and do not cut things too close.

Is $53 a fair price?

At $53 per person, this is not the cheapest short activity in Avalon. The value depends on what you want from the ride.

You are paying for a guided boat trip, the unusual semi-submersible setting, access to the underwater viewing cabin, and the top-deck ride back. For a child who is fascinated by submarines or sea creatures, that combination may feel well worth the cost. The short length is also useful if you want to add one distinctive activity without giving up your whole day.

The price is harder to justify if you expect a long cruise, a large open-water route, or a serious marine biology lesson. The underwater section is limited to six feet and Lovers’ Cove. You see one local area rather than a wide stretch of Catalina’s coast.

The fish-food charge also affects the total. A family of four that adds the $20 food package is spending noticeably more than the headline price. I recommend treating the feeding feature as an optional bonus, not part of the basic ticket.

Compared with snorkeling, the semi-submarine is easier and more inclusive. You stay dry, avoid equipment, and can participate even if you are not comfortable in the water. Compared with a true submarine or scuba excursion, it offers less range and less time below the surface. The fair comparison is not to a full underwater expedition. It is to a compact, family-oriented look at Avalon Bay.

Seating, windows, and motion concerns

Arriving early can help with seating, especially if you want your family together. The maximum group size is 48, and the lower cabin can fill up. A late-arriving group may need to divide among available seats.

Window condition can affect your view. One report noted that one side of the submarine had clear windows while the other side was harder to see through because only one side had been replaced. I cannot promise which side will offer the clearest view on your departure, so choose your seat with care and ask the crew if you are unsure.

Motion sickness is another practical point. This is still a boat ride, and the water can move. If you are sensitive to motion, sit where the crew recommends and consider your usual precautions. The tour is short, but 45 minutes can feel long if the sea is rough and you are uncomfortable.

The activity is listed as suitable for most people, and service animals are allowed. Children must be accompanied by an adult. The boat is near public transportation in Avalon, but your transportation to Catalina itself is not part of the booking.

Who will enjoy the SS Nautilus most?

I would put this near the top of the list for families with young children. The submarine shape, underwater portholes, fish activity, and torpedo buttons give children several things to watch and do. The 45-minute length is also manageable for short attention spans.

It also suits adults who want to see Catalina’s sea life without snorkeling or swimming. You can enjoy the fish and kelp while staying in ordinary clothes. That makes it a practical choice for a mixed-age group in which some people want a marine experience and others do not want to get wet.

The ride may disappoint you if you want a quiet, natural observation trip. The fish-food feature gathers animals close to the boat, and the cabin can be lively when children are excited. It may also fall short if your main goal is extensive commentary about local ecology.

I would not make this the only reason to visit Catalina Island. It is a pleasant add-on to an Avalon day, not a replacement for exploring the town, walking the waterfront, or planning a longer ocean activity. Its strength is convenience.

Timing your tour around the ferry

The tour operator does not provide transportation from the mainland. You must first arrange a ferry to Catalina Island, such as Catalina Express or Newport Flyer, then make your own way to the Green Pleasure Pier in Avalon.

This is the part of the booking that requires the most care. Do not schedule the submarine immediately after your ferry’s planned arrival. Give yourself time for any delay, the walk through Avalon, ticket collection, and check-in. The operator has a strict late policy, and missing the boat does not bring a refund.

Departures run hourly from mid-morning until an hour before the final listed departure, with weather conditions affecting the schedule. That range gives you useful flexibility. A morning ride can leave the rest of the day open, while an afternoon or near-sunset departure may fit better after lunch and sightseeing.

Bad weather can cancel the activity. If that happens, you are offered another date or a full refund. For your own cancellation, you receive a full refund if you cancel at least 24 hours before the start time. Cancellations or changes inside 24 hours are not refunded or accepted.

My take: book it for an easy family sea-life outing

I recommend the Yellow Semi-Submarine Tour if you want a short, simple way to see Catalina’s underwater world while staying dry. The fish can gather in impressive numbers, the setting at Lovers’ Cove is appealing, and the top deck adds pleasant harbor views on the way home.

Book it especially if you have children, non-swimmers, or a mixed group with different comfort levels in the water. Arrive early, bring cash for the optional fish food, and ask how to spread the food across all three stops.

Skip it if you want a long offshore cruise, guaranteed rare wildlife, or a detailed naturalist program. At $53, the activity offers a fun glimpse rather than a full marine adventure. For the right audience, though, that glimpse is exactly enough: unusual, easy, and memorable without requiring a swimsuit.
