I'm not a swimmer and...
I'm not a swimmer and this was easy and a very cool experience. Staff was very accommodating. Only complaint would be that they have very few functional lockers, so we had to leave some stuff with them v locked up.

Very cool, wish it was longer
Had such an awesome time, definitely an experience walking on the ocean floor! Pros: Unique, felt safe, cool experience, great staff, easy once you get used to it Cons: Very short time actually under water, there really wasn't much to look at (no coral to see up close and very little ocean life in that particular area while walking) Improvements: there was a lot of prompting for pictures, like constantly, less would be better so we could actually enjoy the experience. Staff could possibly feed the fish so they're actually around us to see if that's allowed.

Don't Be Afraid to Try
I was very nervous about this, but it was a breeze to do. You step on a ladder on the pier to go down into the water. As you enter the water, they put the helmet on you and it is NOT heavy. It does NOT close around your neck but instead, has air pumped in through a hose. This air is for your breathing and at the same time, forces the water to stay below the helmet. You breathe naturally and the staff reviews hand signals in advance so you can communicate with them. (Several are in the water with you and one was above, floating and watching us while also observing the air hoses.) When the last person was down the ladder, they confirmed that our ear pressure was fine and that we were ready to go for a little walk. There were oodles of fish right in front of us, but not a large variety. They guided us throughout the walk, took our pictures, pulled out a plastic shark from under a rock for a little humor and made it fun. The time flew by and it was time to go up the ladder and share our very positive experience.

Dont' book this Sea Trek
This wasn't what was offered. We were in the water for ten minutes when we were promised 30 minutes at least. Entry was uneven on a rock base, nothing was set up in terms of any rails or ropes to follow. Nothing to guide you and nothing to look at. We have been to Xel-Ha as well Aruba both were great experiences. This was unsafe with nothing to see, nothing to guide you and there was nothing to attract the fish. It was the worse ever. They kept us sitting there indicating people were ahead of us when there was no one and no equipment was put out on the dock until just before 12 noon. Part of our group was booked for 10 am and the other noon and we asked if they could take us all at 10 and they told us no indicating there were groups ahead of us. We were the only group of the day. We were sitting right across at the beach and there were no groups ahead of us or behind us. It was a joke. Misrepresentation.
Response from the operator: Hello! Thank you for sharing your thoughts. However, it looks like some information is just not right. Let's take a look... We strived very hard to give you the best possible experience. The delay was due to your request to dive together with your travel companion who was in a different time slot. Our GM personally traveled all the way from downtown with extra equipment just so you two could dive together. Bottom Time: It looks like your group received full bottom time. According to our surveillance camera, it shows your group entered the water at 12:00 noon and were out of the water at 12:28 PM. We keep the bottom time between 25 to 35 minutes similar to basic SCUBA diving while breathing compressed air. We don't attract fish by feeding them as they may do in other places; this goes against the fish natural feeding behaviors. The fish are usually plentiful. We take our service very seriously, after all, it's our livelihood and misrepresentation is something we DO NOT do. I hope you enjoyed the rest of your vacation. Sincerely,

Why this scores 40
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Sea Trek Adventure at Chankanaab National Park: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Cozumel.
How much does Sea Trek Adventure at Chankanaab National Park cost?
+
Prices start at $79 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Cozumel usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Sea Trek Adventure at Chankanaab National Park take?
+
Plan for about 1.3 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Cozumel is not rushed.
Is Sea Trek Adventure at Chankanaab National Park worth it?
+
It holds an Outty Ranking of 40 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.5/5 across 10 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Cozumel, and how flexible the cancellation terms are.
Can I cancel or reschedule Sea Trek Adventure at Chankanaab National Park?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Sea Trek Adventure at Chankanaab National Park suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1.3-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Sea Trek Adventure at Chankanaab National Park?
+
Around 4 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Cozumel can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Cozumel and add a light layer if any part of the 1.3-hour experience runs outdoors or after sunset.
Where does Sea Trek Adventure at Chankanaab National Park start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Cozumel within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Cozumel?
+
On Outty we rank every Cozumel experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Jade Caverns and Mayan Village Cozumel ATV TOUR, Buggy, Beach & Snorkel Blast, ATV 4×4+Cenote+Snorkeling+Beach Club+ Lunch+Sabores de Cozumel. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Cozumel?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Cozumel?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
