10 hours (full day)
Suitable for most travelers who can board a small boat and swim short snorkel sessions; expect some walking on sand and uneven paths.
A full-day catamaran from Cancun or the Riviera Maya that pairs a reef snorkel with a guided visit to Isla Contoy—Mexico’s protected bird and reef sanctuary—plus a stop in Isla Mujeres. Advance booking is essential: Contoy caps visitors at 200 a day.
The catamaran eases away from the marina and the city’s skyline recedes into a ribbon of heat and glass. Salt spray stings your lips, gulls wheel as if reviewing the guest list, and the horizon opens to a sheet of Caribbean blue that seems to dare you to keep looking. Ninety minutes of slow ocean and the water changes—deeper blues give way to the pale greens of reef flats—and then Contoy appears: a low, forested oval ringed with white sand, its mangroves and palms moving like a crowd of attentive listeners.

Only 200 visitors allowed on Contoy each day—reserve weeks in advance in high season to secure a spot.
The park enforces reef protection; use biodegradable sunscreen to avoid harming coral and marine life.
Shallow reefs and rocky shorelines mean protective footwear makes snorkeling and shoreline walks safer.
There’s a mandatory dock tax (about $20 USD) not included in the price—bring small bills to speed boarding.
Isla Contoy has long been recognized by local fishers; it became a national park in 1998 to protect its seabird colonies and reef habitats.
Contoy’s strict visitor limit and guided tours aim to minimize human impact; visitors are asked to stay on paths, avoid disturbing nesting birds, and use reef‑safe products.
