Sea Trek Helmet Walk at Chankanaab National Park — Walk Underwater in Cozumel
Walk on the ocean floor inside an astronaut-like helmet at Chankanaab National Park in Cozumel. This guided Sea Trek experience requires no swimming skill and pairs a short underwater walk with free snorkeling gear afterward.
The Experience
Before You Go
Arrive early for briefings
Check in at least 30 minutes before your slot to complete waivers and safety briefings; peak season fills fast.
Use reef-safe sunscreen
Apply biodegradable sunscreen before arriving to protect coral and marine life; reapply only where permitted.
Wear closed-toe water shoes
The ladder and shallow sand can be slippery; water shoes make entry and exit safer and more comfortable.
Plan light after your slot
Don’t schedule tight connections—park processing and group pacing can add 20–40 minutes to your day.
