This excursion was great! You start out at AquaWorld and then take a boat ride to the submarine/glass bottom boat. The employees are extremely nice. MAKE SURE YOU BRING CASH TO TIP THEM. There are multiple opportunities to tip, once after the submarine ride where you can tip the mermaid and tour guides, another opportunity to tip the snorkeling tour guides, and then again at the end when you take the boat ride back to AquaWorld. The tour guides bust their butts all day making drinks for people and constantly trying to entertain. I know drinks are technically included, but tip as if you actually had a bar tab! The submarine ride goes through a beautiful coral reef, and underwater museum. I would advise bringing something for nausea if you have a weak stomach because the submarine ride is a little rocky, but definitely not unbearable by any means. The submarine ride lasts about 30 minutes and then there is an area to do the optional snorkeling. I would highly recommend doing the optional snorkeling because it was definitely worth it. You get to snorkel through a coral reef and underwater museum. We even got to see stingrays, vibrantly colored fish, sea turtles, and barracudas!
A huge shout out to our tour guide, Jesus, he was so amazing!!! Jesus was very engaging and cracking jokes the whole time. He did not stop checking up on everybody and making sure they were doing okay. If I could write a whole review just about how great Jesus was I would do it! Overall it was a great experience.

Was Great! Got to see sea turtles, barracuda, coral, and brightly colored fish. They take you from the dock on a boat through the lagoon to the ocean. They have plenty of drinks on this boat. Then you get off the boat and board the Sub See submarine. It is well worth it!

I have just Submarine Tour but it was a wonderfull Tour.

Great experience.
Highly recommended.

A totally different experience of you are sea sick maybe not the tour for you but amazing to see all the fish and coral

Reasonable. Saw very little. All staff fantasic and friendly.

We spent excellent time, thank you! But, please, inform the clients that they should reconfirm departure time not 48 or 24 hours before, but much earlier. Otherwise the operation company Aqua World is likely to charge additional +7,50 USR per person.

The boat, submarine, and snorkeling were great, but the last ten minutes of each involved the crew begging for tips incredibly hard. Our reservation indicated that lunch was included, but we were told that's not available in Cancun. I would do this trip again, but I would bring small bills for tips.

Local provider and the whole service were fine.
I guess we had bad luck - water was rather muddy and hardly transparent.
Some fish were seen and some corals but everything was greyish.
I would recommend to travelers to use their time to enjoy the beaches/pools
and spend their money on cocktails.

Great organization and staff. I was a bit disappointed as I thought there would be more color distinction in the corals themselves being that it is the 2nd largest reef in the world. Volume could be turned down on the system used by the Guide and the tips boxes held by staff while exiting both on the submersible and transportation boat are a bit offensive. Glad I did the excursion though.
