History
Cozumel was a sacred island to the Maya goddess Ix Chel and later became a fishing and diving hub; its reefs have drawn explorers and conservation efforts for decades.
Conservation
The Arrecifes de Cozumel National Marine Park restricts certain activities and limits access to sensitive areas like El Cielo; use reef-safe products and avoid touching coral to reduce impact.

Bring reef-safe sunscreen
Conventional sunscreens harm coral; pack a biodegradable, mineral-based sunscreen and reapply before boarding to minimize reef contact.
Wear a snug mask
Masks provided, but a personal mask that seals well reduces fogging and makes longer swims more comfortable.
Practice the ladder climb
You must climb a ladder to reboard; wear water shoes with good grip and be prepared to hoist yourself out of the water.
Go early for calmer seas
Morning departures often mean smoother water, clearer visibility, and less competition at El Cielo.
Reef-safe sunscreen
Protects your skin and the corals — mandatory for responsible snorkeling.
Swimsuit and quick-dry towel
Comfortable swimwear and a towel for the ride and picnic on return.
Water shoes
Helps with traction on the ladder and protects feet on shallow sand or boat decks.
Light rash guard or UV shirt
Adds sun protection during surface swims and while waiting on deck.
