Imagine walking along the ocean floor without having to worry about breathing equipment or getting wet. That’s exactly what the Sea Trek Adventure at Chankanaab National Park promises — a chance to explore underwater life in a relaxed, accessible way. This tour is designed to give everyone, regardless of swimming skill or experience, the opportunity to enjoy Cozumel’s vibrant marine environment with ease.
What we love about this experience? First, the easy-to-wear Sea Trek helmet makes underwater exploration accessible and stress-free. No need to learn complicated breathing techniques or carry heavy gear. Second, the guided nature of the tour means you’ll get expert insights and safety assurance throughout your underwater walk.
One thing to keep in mind is that the park entrance fee isn’t included in the ticket price, which can add a bit to your overall costs.

Still, for those looking for a gentle, fun introduction to Cozumel’s marine life, this experience can be just right.
This tour suits travelers who want a unique, hands-on experience without needing advanced skills. It’s especially good for those who might be hesitant about traditional scuba or snorkeling but still want to see colorful fish and coral formations up close.

What To Expect During Your Sea Trek Adventure

Starting your day at Chankanaab Beach Adventure Park is straightforward. You’ll arrive at the main entrance, present your booking, and meet your Sea Trek guide. Since the meeting point is within the park, getting there by taxi or car is simple, and it’s worth noting that park entry costs about $23 USD per person, which isn’t included in your ticket.
Once you’re greeted and briefed by your knowledgeable guide, you’ll be given your Sea Trek helmet. These helmets are designed to keep your head and shoulders dry while providing a clear view of the underwater world through a bubble of air. The helmets are comfortable, and most participants find them surprisingly lightweight. After donning your gear, you’ll descend a seaside ladder into the water, guided by your experienced instructor.
The actual underwater walk lasts around 30 to 45 minutes, during which you’ll stroll along the sandy bottom of the reef. The Chankanaab Reef is known for its lively marine life, including colorful fish, coral formations, and other sea creatures. The guides are familiar with the environment and will point out interesting sights, making sure you don’t miss a thing.
For many, the highlight is seeing vibrant schools of fish swimming close by and marveling at the intricate coral structures. The helmet design gives a wide, unobstructed view, creating the feeling of walking in a giant aquarium. Plus, the fact that you stay dry means you can focus purely on the sights without worrying about water getting into your eyes or your hair.
After completing your Sea Trek, you’re welcome to continue exploring the reef with the snorkel gear provided. This allows you to extend your underwater experience if you’re eager to see even more of the marine life at your own pace.

The Practicalities: Pricing, Duration, and What’s Included

The overall price for this tour is $79 per person, which for a unique underwater walk is quite reasonable. When you factor in the fact that you’ll get the special helmet gear, lockers, showers, and snorkeling equipment afterward, the value begins to look favorable, especially for those wanting a hassle-free underwater encounter.
Keep in mind, the park entrance fee is separate, roughly $23 USD, so plan for that additional expense. The entire experience lasts about two hours, making it easy to fit into a half-day excursion. Tours are typically available in the morning and afternoon, so you can choose a time that works best with your schedule.
The included snorkeling gear after the Sea Trek is an excellent bonus, allowing you to explore more of the reef without extra costs. The lockers and showers provided at the park mean you can freshen up afterward comfortably.
