Family Fun

This is a nice tour for all ages. We took adults & seniors and everyone enjoyed it. A heads up, there are steps involved, so make sure your group members are able to independently get up & down the steps.
Good for kids 3.75 stars
, Aug 2022
Pros: Great for kids Staff friendly Cons: Air conditioning unit drips all over us, wet seat, shirt and backpacks Was nice experience but nothing really outstanding
Got wet inside the sub
, Aug 2022
Except for water dripping from the AC (hopefully) my head and clothes getting wet, it's a cool experience. We enjoyed feeding the fishes.

Family enjoyed the experiences with all the marine life surrounding the vessel. Thank you for the experience
Beyond expectations
, Jul 2022
Best submarine trip ever. The fish come up to the window when you feed them through a paid food source launcher. The fish were ready for the submarine and eagerly swam up to the windows. The seaweed was plentiful and up close. Highly recommend this voyage.
Nice adventure!
, Jul 2022
It was a nice adventure. You cannot be claustrophobic to do this trip. Everything was clean and nice.

My son loved it. My only complaint is that the ticketing system is horrible especially if you buy ahead of time online. We had to wait for paper printed tickets which took 45 minutes to retrieve. Digital tickets should be efficient to present at the Semi-sun line at entrance
Sh@t show
, Jul 2022
Waited in line for 30 minutes to get good seats just to be told that we needed printed tickets. There was no mention whatsoever when we booked and in fact was given the option to add it to my apple wallet. The guy was incredibly rude. He was also yelling at kids to “get back” when they were just standing there. Lost my place in line. I couldn’t wait for this tour to end. The windows in the sub were badly scratched so not at all clear. $180 for my family would have been better spent on a casual snorkeling trip. Complete waste of money.
It’s a must!!

The staff was beyond helpful and interactive with us and my kids had a blast. It’s a must while in Catalina
Do NOT EVER book this tour
, Jul 2022
Worst experience dealing with these people. Me and my family did NOT get to go on the tour because of the worst customer service I’ve ever experienced and lack of communication between the owner of the boat and the check in. I would give it ZERO stars if possible. I will NEVER DEAL WITH THIS AGAIN. We were told to go stand at the Letter E to be called to the boat. Not once were we told to go down to the boat and just walk on. The man on the boat saw us standing there and not once told us to come down or if we were part of the tour. We were on time! The boat just closed and took off. It was the last boat of the day and we were leaving in the in the morning g and couldn’t catch another one. The lady that TOLD us to stand there and wait was the absolute RUDEST customer service employee I’ve have ever dealt with. Would not give us the name of the owner of the boat, her managers name, her name and yelled at us when we were just trying to get answers or a name of the boys owner to ask him questions and leave her alone. She made the situation worse. So me and my family wasted $221 to watch the boat go away. I will never again book this tour or anything through this company. I will talk to the necessary people to make sure this is dealt with.

It’s an awesome and amazing experience! =)) I and my daughter enjoyed the adventure and to add to that, the guys are very nice and taught us a lot of stuff we didn’t know about fishes.
Enjoyed it!
, Jul 2022
Every thing was lots of fun until on the way back the sub started getting rocky and a couple of us thought we were going to be seasick, but other than that we had a great time. We got to see lots of tropical fish and the kids were very excited.
Kids will love it

Kids enjoyed a lot, it’s worth the price. Even adult enjoyed fishes and feed food to fishes from submarine.
Must try! Great experience!

Overall fun but they need a better seating system so we don't have to fight for a place to sit. Some people took up more seating and had to be made to share room.

Had a great experience

, Jun 2022
Really fun. Got a little woozy but it went away in no time. It was beautiful. I would definitely do it again and refer others!
Fun for kids - but too expensive.
, May 2022
The kids had a great time. The ticket is overpriced. Especially when they tack on additional cash charges for fish food once your in the sub. It felt a little like a scam. Especially when the ticket was like $45 a pop. That said… kids under 10 will Love it.
