Light to moderate: comfortable in ocean water and able to swim short distances; non-swimmers should use a life vest.
Catch the ferry from Playa del Carmen for a day exploring Cozumel’s national marine park: two guided snorkel sites, a buffet lunch, and abundant reef life. This full-day trip balances easy ocean access with guided safety for families and first-time snorkelers.
The morning ferry slips out of Playa del Carmen with the smell of diesel and sunscreen in the air, and within an hour the shoreline thins to a green thread. Cozumel rises from the Caribbean like an invitation: low, limestone coast, scrubby palms, and a reef that refuses to stay quiet. By the time the crew rigs gear, the water has already started to call—cool, clear, and confident.

Use mineral-based sunscreen or a rash guard to protect coral and reduce the need for frequent reapplication in the water.
Test and adjust your mask on shore; a snug seal prevents leaks that ruin underwater visibility.
Follow your guide’s instructions about entry points and hold the surface float line if currents pick up near wall sites.
Keep phone, extra cash, and ID dry—boats have limited storage and shore stops can be windy.
Cozumel was an important navigational and pilgrimage stop for the Maya and later became protected as part of Mexico's national marine park to conserve its coral systems.
The marine park enforces mooring and snorkeling rules to reduce anchor and contact damage; visitors are encouraged to use reef-safe sunscreen and avoid touching corals.
Personal gear often fits better and reduces fogging and discomfort.
Protects from sun, jellyfish, and keeps you comfortable in cooler mornings.
