Traveler Reviews

It was awesome! Especially interacting with the fishes. How close they got to the window. I highly recommend it.

Amazing! The views of kelp and variety of fishes were so beautiful, especially the colorful Girabaldi fish. The first mate gave us great details about the life cycle, food, and history of all these flora and fauna.

We originally booked a glass bottom boat tour, but it was cancelled due to maintenance, and Catalina Tours immediately called to notify us and upgrade us to the Undersea Expedition for no charge. A variety of fish come right up to the windows with no fear. If you get seasick, they will let you up on the deck for some fresh air, but that can easily be prevented by not drinking too much liquid beforehand, wearing sea bands on your wrists and snacking on some Saltines or other dry crackers. Definitely a crowd pleaser, especially for the kids.

Went with my 8 year old- was nice- it is exactly what you think, nothing more- maybe 3-5 types of fish that wait for the boats to come and eat… is it worth the money? Hmmm debatable but it delivers schools of fish. After 20 minutes my son was playing with a toy we brought..

It was a fun ride. We saw lots of fish only maybe 5-6 different types but lots of them. I have 1.5 year old and she was entertained and had fun. My husband gets super seasick and he was fine. We would do it again.

Everything was great 😊 I would highly recommend this excursion & would likely do it again. …………………………….

I really enjoyed the expedition. The tour staff were all friendly and informative. It was great seeing all the marine life.

The boat over there had an emergency and we turned around and went back to Newport and then back to Catalina. Took 3 hours and our day was wasted away.

The tour was so fun. On the guide was funny. So glad I went, I will for sure be doing this again. Loved it

Did you know that there are TWO companies offering submarine tours in Catalina? Neither did I. The one I booked, Catalina Island Company Undersea Sub Expedition (the red boat), was the more expensive tour. This is ironic because the boat didn’t seem so well maintained. Seaweed was growing around the edges of the windows, and the glass had goop marks and haze from stuff growing on it. We were booked for a 1:00 p.m. cruise, and they requested us to be at the dock in line by 12:40p. Then the crew made us stand in line, on the dock in the sun with no shade, while they finished lunch. We watched one of them eat a sandwich. We waited twenty minutes, outside at midday, something that I would never do normally. So I was subsequently surprise-sunburned pretty bad. After we boarded, I was disappointed to find that the submarine windows were caked and framed in seaweed, growing outside of the sub window seals, and waving with the water into the window. My window also had a large glop of algae in the middle. The semi-submersible tour was pleasant enough. The captain of the sub is a local who grew up on Catalina. He and the crew kindly offered a narrative of the fish and the reef as we motored about the bay. The experience of seeing fish in a natural setting is really quite lovely, once I was able to ignore the seaweed swirling and flopping about NOT on the ocean floor but around the edges of my window. Everyone was friendly. But next time I’ll book the other company (the yellow boat) and hope for a better overall experience.

Catalina Island tours vary in cost. A more in-depth private sightseeing tour costs around $300 for a group while a shorter submarine underwater tour costs around $50 per person.

On Catalina Island, you can find a variety of excursions and tours for different group sizes and budgets.

What is the best month to go to Catalina Island?

I personally enjoy visiting Catalina Island in the spring and early summer months when the rolling hills are covered in green grass and lush vegetation. But Catalina Island is a wonderful destination to visit year-round due to its mild, temperate weather.

Is it worth going to Catalina Island for the day?

I’ve gone to Catalina Island on day trips and it is so worth it! Due to its close location to the Southern California coast, you can easily plan day trips to Catalina and explore quite a bit within a few hours.

The Catalina Express boats depart from Long Beach, San Pedro, and Dana Point . I live the closest to Long Beach so this is where I usually leave from.

As a second option, you can arrange a ride with Catalina Flyer which departs from Newport Beach in Orange County. This is the largest catamaran on the California Coast that also offers multiple round trip options daily.
