Isla Mujeres has some of the easiest and most rewarding diving in the Mexican Caribbean, and the classic outing is a two-tank morning on the Manchones reef and the underwater museum known as MUSA. Manchones is a long, shallow reef off the south-western side of the island, with coral ridges, sand channels and plenty of fish, turtles and rays, and the MUSA installation nearby holds hundreds of life-size concrete sculptures that have become an artificial reef colonised by corals and sponges. Both sites are shallow, typically around eight to twelve metres, with gentle conditions on calm days, which makes them ideal for newly certified divers and for anyone who wants relaxed, photogenic dives close to shore.
The dives
Boats leave from the island's dive shops in the morning and reach the sites in a short ride. On the first dive you explore the reef, looking for parrotfish, grunts, snappers, moray eels, lobsters, nurse sharks and turtles. The second dive visits the sculptures, including the famous circle of standing figures known as the Silent Evolution, now encrusted with marine life. Dive guides lead small groups, and equipment, tanks and weights are normally included, though you should check whether rental gear costs extra.
Who can dive
The two-tank trip is for divers with an open water certification or equivalent, and you should bring your card and logbook. If you are not certified, many dive centres offer discover scuba programmes with a pool or shallow-water session followed by a supervised dive, and full open water certification courses take several days. Snorkellers can see the shallowest MUSA sculptures and parts of the reef on snorkel trips. Remember that you should not fly within roughly a day of diving, so plan dives early in your stay.
Season and practicalities
Diving runs year-round, with the calmest seas and clearest water usually in the dry season, while winter cold fronts and summer storms can cancel trips for a day or two. Water temperatures are warm all year, so a thin wetsuit or rash vest is enough for most people. Go with an established dive centre that follows reef-protection rules, and never touch the corals or sculptures. In summer, combine a morning of diving with a whale shark trip on another day for a superb marine week.
