We couldn’t understand the guide because of a heavy accent. Because of so much feeding, it was hard to see the kelp and find other kinds of fish. Too much money for a less than memorable experience.

Thank you for your review. We are sorry your experience wasn't what you had hoped.
, May 2022
Rude staff, basically circles around a fishbowl and comes back over feeding local wildlife along the way
Feeding the fish
, May 2022
Feeding the fish was really fun. I loved watching them get so close especially the orange and blue ones.
Great for Kids
, May 2022
This is a great experience for kids. The sub provides information on the various fish and children (as well as adults) are able to push buttons to feed the fish in the ocean.
No email

Catalina express canceled our boat and they wouldn’t refund us. I emailed them and no response was sent to us. I understand the cancellation policy but the cancellation was not up to us.

Hello. Would you be able to call or send a email regarding your experience. We do offer refunds in case of weather related cancellations. I would be happy to help you.

Love that it was something different. Got to see lots of fish and the tide in a fabulous job. Would definitely recommend this.
It was a good time.
, Apr 2022
We went on a Wednesday and it was not real crowded. The tour guide is very friendly and informative. A good amount of sea life is visible.
Fun In The Sub!
, Apr 2022
It was amazing to pull up to the first reef and push the red button which fired the food! I thought it would scare the fish, but it didn’t. Instead they swam right to it! They were so close you could touch them.
Not for Adults with children older than 10.
, Apr 2022
This is for very small children. Not for children order than 10. Not worth what they charged and than you have to pay to feed the fish which is stupid cost also. Would not have did this if I knew it was less than 30 minutes.
Great service, even better jokes
, Apr 2022
Both of the men hosting it were so funny and very helpful. Very kind and informative, made the trip so worth it.
Would recommend it was great

Absolutely amazing. This was so beautiful. And it was east I picked out the tickets the day before. 5 stars
Fun 😀
, Apr 2022
Fun with the kids age 9,6 and feeding the fish was a great distraction from my otherwise easily sea sick so . He did great!
So much more exciting than I anticipated--well worth the cost!
, Apr 2022
Truly amazing experience, right in the middle of the kelp forest with garibaldi fish, opal eyes, rock bass and more. Kids had so much fun "shooting" fish food from the torpedoes and seeing the fish swarm around. I expected more of a "Finding Nemo" experience like at Disneyland, but this was enthralling for kids and adults as well. So comfortable inside, and the staff shared wonderfully educational information. Well worth the cost!
Wonderful Views
, Apr 2022
Not a lot of species in the environment, it's about six or less that were present. Regardless of that, it was still a wonderful view and the water was clear enough to see the fishes in our window.
Great little tour
, Mar 2022
Great tour. Saw some cool fish and underwater habitat. Great tour for the price. Tour guide was great as well
Family fun
, Feb 2022
Great fun for kids and family alike. This experience is better than the Great Barrier Reef where the food torpedos attracts tons of fish albeit without the variety though.
, Feb 2022
It was nice and truly neat to watch the fish and look at the seaweed. It was peaceful and worth the cost.
Best submarine
, Jan 2022
Love the fact that we get to feed the fish and they come and are near the window that’s the best part
Great experience
, Dec 2021
It was a lot of fun! The guide was great! It was awesome to see all the fish. Our son had a great time feeding them.
Sub 10 plus
