You should be a competent swimmer with moderate fitness—able to snorkel for multiple 20–30 minute intervals and climb a ladder back onto the boat.
Float over gardens of coral, drift among parrotfish, then wade into the shallow, starfish-strewn sands of El Cielo. This private Cozumel snorkel tour pairs top reef sites with an exclusive stop at a protected sandbar for a compact, high-value marine day.
The engine cuts to a steady hum and the Caribbean yawns open: cobalt close to shore, lighter toward the horizon. You step aboard at FONATUR Marina while the guide checks fins and hands out sanitized snorkel sets. Within twenty minutes the reefs arrive—first Colombia and then Palancar—walls and gardens where parrotfish graze and corals angle into currents that dare you to look closer.

Photodegradable sunscreens protect coral—apply at least 20 minutes before boarding and reapply after snorkeling.
A lightweight UV shirt reduces sunburn and offers slight thermal protection during windier crossings.
The boat crosses open water; if you’re prone to nausea, medicate 30–60 minutes before departure.
Know how to clear your snorkel mask and breathe calmly—guides expect self-sufficient swimmers.
Cozumel’s reefs have long supported local fisheries; the National Marine Park, established in 1996, shifted the island toward tourism and protection of reef resources.
El Cielo is permit-controlled to limit impact; visitors must avoid handling starfish or corals and use reef-safe sunscreens to minimize chemical damage.
Bringing a personal mask can improve fit and comfort in the water.
