Isla Contoy National Park: A 200-Visitor Island

Isla Contoy National Park admits a maximum of 200 visitors per day, enforced by CONANP, Mexico's protected-areas commission. The island lies about 30 kilometers north of Isla Mujeres, where the Caribbean meets the Gulf of Mexico, and you can only land there on a licensed tour boat. No hotel, no restaurant, no road, no resident — just an 8.5-kilometer strip of sand, mangroves and seabird colonies.

That cap is the reason the place still feels wild. On my last crossing the only other people in sight were a dozen snorkelers and a ranger counting heads at the dock. Compare that to Playa Norte on Isla Mujeres on the same afternoon, and the difference is stark.

What Makes Contoy Different

A bird sanctuary first, a beach second

The island is one of the most important seabird nesting sites in the Mexican Caribbean — more than 150 species have been recorded, including magnificent frigatebirds, brown pelicans and blue-footed boobies. Four species of sea turtle nest on its beaches. It was declared a federal wildlife refuge in 1961, upgraded to a national park in February 1998, and listed as a Ramsar wetland in 2003.

Because of that status, access is managed like a research station rather than a resort. Tour groups follow marked interpretive trails, and a certified guide is mandatory. When I visited, our guide stopped the group at the lagoon boardwalk for ten minutes just to watch frigatebirds inflate their red throat pouches — a detail most beach-focused tours would skip.

The sargassum question

Contoy's public beach sits on the sheltered side of the island, and it is usually free of the brown seaweed that plagues Cancún and Tulum between April and October. The reef and currents around the island keep most of it offshore. That said, no beach is guaranteed — check conditions close to your travel date, because wind can push sargassum anywhere in the region.

Planning Your Visit

Getting there and tour logistics

There is no public ferry. Every visitor arrives by boat with an authorized operator, typically departing from Punta Sam in Cancún or from Isla Mujeres. Crossings take 30 to 45 minutes and can be choppy, especially from the Cancún side. Most boats leave between 9:30 and 10 a.m. and return in the afternoon.

Shared day tours run roughly US$139–179 per person and usually combine Contoy with a snorkel stop at Ixlaché reef and a short visit to Isla Mujeres. Full-day trips last 6 to 10 hours depending on your pickup point — Riviera Maya and Playa del Carmen departures add road time. Book at least a month ahead in high season (December through April); with only 200 slots a day, the good operators sell out.

Fees and what you pay in cash

The federal park fee is 225 MXN per person per day (about US$12–13), set by the Ley Federal de Derechos. Many tours do not include it and collect a combined park-and-dock fee of around US$20 in cash at the marina or on arrival. Bring small bills. Children under 12, seniors with INAPAM credentials, pensioners and visitors with disabilities are exempt; students and teachers with valid ID get a discount. Rates change — confirm the current fee with CONANP or your operator before you go.

Rules that actually get enforced

Single-use plastics are banned, and cigarettes are not allowed on the island. Conventional sunscreen is prohibited because it damages coral — bring biodegradable formula or wear a rash guard. Drones are not permitted. Groups are limited to 10 visitors per guide, and there is no overnight stays of any kind. The rangers at the dock do check bags.

What to Do on the Island

Snorkeling at Ixlaché reef

The reef stop happens before you land, weather permitting. Visibility is often excellent, with parrotfish, angelfish and occasional sea turtles. Currents can be strong where the gulf and Caribbean meet, so this is not the spot for a first-time snorkeler who is nervous in open water. Some operators set a minimum age of 12 for the snorkel portion — worth checking if you are traveling with younger kids.

Trails, lagoon and lookout tower

A guided walk covers the central lagoon, the dune trail and a lookout tower with views over the mangroves. The small natural history museum at the visitor center displays exhibits on island ecology, sea turtles and the whale shark. Plan on roughly two hours of free beach time on a standard tour — enough for a swim and lunch, not enough to feel rushed.

Birdwatching by season

Nesting season runs roughly May through October, when frigatebird and booby colonies are at their most active. Spring migrations bring additional species. Binoculars are worth packing; the observation platforms put you close to the colonies without disturbing them.

Frequently Asked Questions

Can I visit Isla Contoy without a tour?

No. Access is limited to authorized operators, and private boats are turned away unless access was arranged with the park office in advance. Independent travelers would need a permit from CONANP, which is rarely granted to individuals.

How much does a day trip cost in total?

Budget US$159–199 per person for a shared tour plus the park fee, which is often collected separately as about US$20 cash. Private charters for groups of four or more can bring the per-person cost to around US$210.

Is Isla Contoy suitable for children and older visitors?

The beach and guided trails are easy, and kids under 12 enter the park free. The open-water reef snorkel is the main limitation — check minimum-age rules with your operator, and note that boats are not wheelchair accessible.

When is the best time to visit?

December through May offers the driest weather and calmest seas. January can bring northerly winds that close the port entirely, so build a buffer day into your plans if Contoy is a priority.
