Sea Trek at Chankanaab: Walk Underwater in Cozumel's Marine Park
Step into a transparent helmet and walk the sandy floor of Chankanaab National Park while colorful reef fish thread through the water around you. Sea Trek makes underwater exploration accessible to non-swimmers and families, pairing a brief safety briefing with a unique, guided ocean stroll.
The Experience
Before You Go
Arrive 20 minutes early
You must check in 20 minutes before your start time to complete paperwork and safety briefings—late arrivals may lose their slot.
Bring cash for park entrance
Chankanaab offers a discounted entrance price that must be paid in cash at the gate—have small bills ready.
Wear water shoes
A sandy bottom can hide coral bits; water shoes protect feet when stepping on the shoreline ladder and while snorkeling afterward.
Avoid scheduling tight connections
Groups are small and operations can slow during high season; don’t book time-sensitive activities immediately after Sea Trek.

Chankanaab was protected in response to reef degradation and overfishing; the park has long been a site for conservation education and sustainable tourism on Cozumel.

How long is the experience?
The full visit is about 80 minutes including briefing, helmet time and a chance to snorkel afterward.
Can I bring a camera?
Yes—small waterproof cameras or housings are recommended; phones should use an approved waterproof case to avoid fogging.
Is the site wheelchair accessible?
Chankanaab Park has wheelchair-accessible facilities and transportation options, but helmet-dive access requires descending a seaside ladder, so check accessibility needs with the operator ahead of time.
What if I have a health condition?
Sea Trek is not recommended for people with serious spinal, cardiovascular issues, or pregnancy—consult your doctor and inform staff of any medical concerns.
