You push off from the small harbor at San Miguel as gulls quarrel over the dock—within minutes the shoreline slides away and the sea widens into cobalt. The boat hums toward Columbia Reef first, where vertical walls and swim-throughs drop into deep blue and schools of parrotfish cut ribboned paths through branching coral.

History
Cozumel’s reefs sit on the northern edge of the Mesoamerican Barrier Reef; the island was an important ritual and fishing site for the Maya and later a strategic stop for Caribbean mariners.
Conservation
The reefs face pressures from warming waters and boat traffic—follow guides’ reef‑safe practices, avoid anchoring on coral, and use designated entry points to limit impact.

Use reef‑safe sunscreen
Apply a mineral-based sunscreen before arrival and bring a light cover-up—chemicals in many sunscreens damage coral and are often prohibited in marine parks.
Fit your mask ashore
Try and seal your snorkel mask at the dock to avoid wasting time adjusting in the water; a good fit prevents fogging and water leaks.
Bring motion‑sickness prevention
Boat rides between reefs can be bumpy; take an over‑the‑counter remedy before sailing if you’re susceptible to seasickness.
Respect wildlife distance
Do not chase or touch sea turtles, manta rays, or starfish—stay still and let animals approach for safer viewing and photos.
Mask & snorkel (or upgraded fit kit)
A well‑fitting mask prevents leaks and lets you focus on marine life; premade gear is provided but many bring their own.
Reef‑safe sunscreen and rashguard
Protects skin from sun and minimizes coral damage—wear a long‑sleeve rashguard for extra sun protection.

Towel and quick‑dry layers
Useful for post‑snorkel comfort and layering against wind on the return ride.
Waterproof camera or smartphone housing
Capture underwater moments—use a wrist strap and keep a dry bag on deck.
