Basic to good swimming ability required; comfortable treading water and climbing a ladder back onto the boat.
Float over Colombia and Palancar Reefs, then wade into the shallow, starfish-strewn El Cielo sandbar on a private 5‑hour snorkel tour from Cozumel. Expect clear water, attentive guides, and a beach picnic after the snorkeling.
The boat slips away from the FONATUR marina and the mainland noise thins behind you—only the engine’s pulse and the reef’s low, constant call remain. In fifteen minutes the water turns a luminous turquoise; beneath the surface the reef arranges itself like a living map. You kick out over Colombia Reef and the ocean opens its doors: brain coral domes, parrotfish nipping at algae, and the reef’s textured ridges steering your path. The guide points and you drift, buoyed by a mandatory vest, while currents nudge you gently along garden walls that have been alive long before tourism arrived.

Apply reef‑safe sunscreen before boarding to protect coral and avoid applying in the water; bring a hat for sun breaks on deck.
A pair of water shoes helps when boarding and walking on the sandbar—some spots are rocky or occupied by starfish so step carefully.
Drink water before departure and sip between snacks; dehydration increases seasickness risk and reduces stamina in the water.
Know how to clear your snorkel mask and breathe calmly—guides expect participants to be self‑sufficient in the water.
The reefs off Cozumel are part of the Mesoamerican Barrier Reef and have long been a fishing and navigation area for Mayan and later coastal communities.
El Cielo access is limited by permit to protect starfish and seagrass; choose operators that collect the marine park fee to fund patrols and restoration.
Protects your skin and the coral—apply before boarding.
