Most visitors to Cancún never make it to Isla Contoy. They hear about it, think it sounds amazing, and then default to yet another crowded group tour to Isla Mujeres. That's a shame — because Isla Contoy is, by a wide margin, the most pristine, untouched, and genuinely wild island accessible from Cancún. A private boat tour to Isla Contoy is one of the most special things you can do in the entire Mexican Caribbean.
This guide covers everything you need to plan your Isla Contoy day trip: what makes the island so special, how a private charter compares to a group tour, the permit requirements, what to do when you're there, and how to combine Contoy with a stop at Isla Mujeres on the way back.

Why Isla Contoy Is Unlike Any Other Island in the Caribbean
Isla Contoy sits roughly 30 kilometers north of Isla Mujeres, about 90 minutes by private boat from Puerto Juárez in Cancún. It is Mexico's smallest national park — just 8.5 kilometers long — and it has been federally protected since 1961. There are no hotels, no restaurants, no beach clubs, and no vendors. The Mexican government limits daily visitors to approximately 200 people per day across all authorized operators, which means even on a busy day, the island feels remarkably empty.
The island is a UNESCO-recognized bird sanctuary supporting more than 170 species, including magnificent frigatebirds, brown pelicans, olivaceous cormorants, and red-footed boobies that nest in the mangroves year-round. The surrounding reefs are exceptionally healthy — visibility regularly exceeds 20 meters, and the marine life includes parrotfish, sea turtles, nurse sharks, eagle rays, and large schools of snapper. If you've been snorkeling elsewhere in Cancún and felt underwhelmed, Contoy will recalibrate your expectations entirely.
Private Boat Tour to Isla Contoy vs. Group Tour: What's the Real Difference?
You have two options for reaching Isla Contoy from Cancún: a group tour or a private boat charter. Understanding the difference helps you decide which is right for your trip.
Group Tours ($80–$120 per person)
Group tours to Contoy typically depart from Puerto Juárez at around 8:00 AM on a large catamaran carrying 25–40 people. They include a snorkeling stop, a guided walk on the island, lunch (usually fish or chicken prepared on board), and an open bar. The experience is organized and competitively priced, but you're sharing the island with a large crowd, following a rigid schedule, and have no flexibility over where you stop or how long you stay.
Private Catamaran Charter from Cancún (from $1,750/charter)
A private boat tour to Isla Contoy means the vessel — and the entire day — belongs to your group. Nauty 360 charters for Contoy typically depart from Puerto Juárez between 7:30 and 8:00 AM and accommodate groups of up to 12 people. Your captain and crew are dedicated exclusively to you. You choose your snorkeling spots, how long you spend on the island, and whether to add a stop at Isla Mujeres on the return. You bring your own food and drinks — or pre-order a private catering package — and enjoy the journey at your own pace.
For families, honeymooners, bachelorette groups, or anyone who values privacy, the per-head math often makes a private charter surprisingly reasonable: a group of 8 splitting a $1,750 charter pays about $219 each.
The Journey from Cancún: What to Expect at Sea
Your Contoy Island boat charter from Cancún departs from Puerto Juárez, located about 3 kilometers north of the Hotel Zone. The crossing takes approximately 90 minutes each way in calm conditions. The route passes Isla Mujeres to the east, so you get beautiful views of that island's white sand coastline as you head north into open Caribbean waters.
Sea conditions vary. The sea is calmer from May to November. Your captain will advise on timing and route adjustments. The journey itself is a highlight: flying fish are common, and it's not unusual to encounter spinner dolphins surfing the bow wake during the crossing.
Practical tip: depart early. The island's daily visitor cap means all groups aim for a mid-morning arrival. An 8:00 AM departure puts you on the island before the crowd and on the reef during the best morning light.
What to Do on Isla Contoy
Time on the island is typically 2–3 hours, split between the beach, the trails, and the reef.
Snorkeling the Outer Reef
The snorkeling at Contoy ranks among the best in the Mexican Caribbean. The reef on the eastern (windward) side of the island features dense coral formations, enormous sea fans, and some of the healthiest fish populations you'll find north of Cozumel. Your crew anchors offshore and snorkelers enter via the swim platform. Common sightings include green and loggerhead sea turtles, nurse sharks resting under coral ledges, spotted eagle rays, queen angelfish, and large schools of blue tang. Bring an underwater camera — a GoPro or similar — because the photo opportunities are exceptional.
The Birdwatching Tower and CONANP Museum
A short walk from the beach leads to a wooden observation tower that rises above the mangrove canopy — the views over the lagoon and the surrounding reef are stunning, and the birdlife is extraordinary. Adjacent to the tower is a small CONANP-run museum with exhibits on the island's ecology, nesting species, and conservation history. It's modest but genuinely informative, and the rangers are enthusiastic and knowledgeable (many speak English).
The Beach
Contoy's main beach on the western (leeward) side is a long, undeveloped stretch of white sand backed by sea grape trees and palms. There are basic bathroom facilities maintained by CONANP. Bring your own snacks, sunscreen (reef-safe only — chemical sunscreen is prohibited on the island), and shade if you want it. The beach is occasionally visited by nesting sea turtles, and the snorkeling directly off the shore in the shallows is excellent for seeing starfish and small rays.
Permits and Entry Requirements for Isla Contoy
Access to Isla Contoy is tightly regulated by CONANP (Comisión Nacional de Áreas Naturales Protegidas), Mexico's national protected areas authority. All visitors must arrive with an authorized, licensed tour operator — independent boaters without an operator permit are not allowed to land.
There is no extra park fee on our Contoy trips. Your charter captain handles the permit paperwork in advance.
Important environmental rules enforced at the island: chemical sunscreen is strictly prohibited (reef-safe mineral sunscreen only), feeding wildlife is banned, no sand or coral removal, no drone flights, and groups must stay on marked paths during land visits. These rules are enforced by on-site rangers and are worth taking seriously — Contoy's pristine condition is directly attributable to this level of protection.
