The waters around Isla Mujeres put several exceptional destinations within easy reach.
Cancún is the obvious base for many visitors to the island — a short ferry hop away and a useful launchpad for exploring the broader Yucatán Peninsula. The city itself is less interesting than its surroundings, but the archaeological museum and the Hotel Zone's access to mainland transport links make it a practical stop.
Cozumel, Mexico's main Caribbean diving island, is the serious diver's destination in this part of the world. The Palancar Reef system around Cozumel is among the finest in the Western Hemisphere — wall dives, spectacular coral formations, and visibility that regularly exceeds 30 metres. Day trips from Isla Mujeres require a ferry to the mainland and then another to Cozumel; it makes more sense as an overnight or multi-day trip.
Isla Holbox lies about 150km to the northwest along the Yucatán coast, accessible by bus from Cancún and then a short ferry from Chiquilá. It shares Isla Mujeres' unhurried character — no cars, sand streets, hammocks in the water — but the vibe is more remote. The waters off the north coast of Holbox are part of the same whale shark aggregation zone, making it an alternative base for whale shark trips from May to September.
Isla Contoy, a small uninhabited island and national park about 30km north of Isla Mujeres, is one of the most important seabird nesting sites on the Mexican Caribbean. Frigatebirds, boobies, pelicans, and dozens of other species nest here in large numbers. Access is controlled — only authorised tours are permitted, and visitor numbers are capped daily. Tour boats depart from Isla Mujeres in the morning; the trip includes snorkelling, a walk on the island, and lunch.
