Undersea Expedition: Catalina Island Tour
Description
Descend 5 feet beneath the surface of one of California’s most extraordinary marine ecosystems, all from the comfort of your own personal porthole in our semi-submersible. Gaze at Giant Kelp forests rising from the ocean floor as large schools of calico bass, bright orange garibaldi, and the occasional diving cormorant or seal pass by to say hello. The top of the boat always remains above the surface in case you need to head upstairs for some fresh air! Our captain also offers a harbor cruise on the ride back to the dock so you can look for dolphins and enjoy the ocean breeze while taking in the stunning views of Avalon.

My family 9 adults and teenagers, we had a great experience on the boat. To see so many fish and learn about each type of fish. It was fun! I recommend this experience to all ages. It was beautiful and so excited.
Not worth the money. Go to Bass Pro and look at the fish tank and save your money.

The crew & boat were great! So very interesting seeing all the fish below. If I had one thing to change, it would be that it was longer? Maybe more time on top and even if that means the ticket prices are a little bit higher. Everybody was great and I thoroughly enjoyed it, will definitely come back and recommend to others.

The underwater experience was a lot of fun. We enjoyed the wide variety of fish we saw up close. The crew was very friendly and knowledgeable.
Thank you so much for your kind review! We’re thrilled to hear you had such a fun experience and enjoyed seeing such a great variety of fish up close on the Undersea Sub Expedition. We hope to welcome you back again soon for another adventure!
An amazing immersive experience where you get to see fish (multiple varieties) and underwater plants up close. A highly recommended experience.
Thank you for your kind words! We’re so happy to hear you enjoyed the Undersea Sub Expedition. There’s nothing quite like seeing Catalina's vibrant marine life up close. We truly appreciate your recommendation and hope you’ll join us again for another adventure!
We saw LOTS of fish, thanks to the generous feeding tubes!! The temperatures were nice and the ride was fun. All good!!
Thank you very much for your high star rating! We're happy to hear that you had a great time on the Undersea Sub Expedition and saw a lot of marine life!
This is a fun short excursion when in Avalon. To say we say fish would be the understatement of the year. There were thousands of them all over the ship. My 18 year old son even managed to enjoy himself. Highly recommended!
Thank you for your feedback! We are so glad to hear that you and your son had a great experience on the Undersea Sub Expedition. We hope to see you next time!
Awesome view of the sea life when you get to lovers cove. 4 o’clock was a good time for visibility. The man kept us entertained and had lots of information for us about all the fish.
Thank you for your wonderful review! We're so glad you enjoyed your time on the Undersea Sub Expedition.
The staff was friendly and welcoming, which truly made the experience stand out. While we didn’t see larger sea life like dolphins, sea lions, whales, or sharks, we did get to enjoy a variety of fascinating fish. It was especially fun to watch them gather around the boat during feeding time—they clearly recognize it and come right up! What really sets any experience apart, though, is the staff. Their positive attitude and kindness can make or break a trip like this, and they absolutely made it memorable. For that reason, I’m happy to give this a five-star review.
Hi Sara, thank you kindly for your review. We're so glad to hear you enjoyed the Undersea Sub Expedition and found our staff to be kind and accommodating. We hope to see you again soon for another adventure!
It was a good experience, I would recommend cleaning the glass from the outside for better view and maybe offering more options in terms of time. Maybe if we go a bit far away from the Island we will see more fish variety.
Hello, and thank you for your review. We appreciate your honest feedback, as we are always looking for ways to improve the guest experience.
