Just off the coast of Cancun, Isla Mujeres is home to a dive site known as the Cave of the Sleeping Sharks. Discovered in 1969 by an island resident, the cave is home to sharks that appear to be “sleeping” instead of constantly moving like they typically do. It’s a mysterious natural wonder that has baffled some divers and marine biologists.
The cave sits roughly 60 feet (20 meters) underwater and can be reached on dive tours from Isla Mujeres. If you’re coming from Cancun, hop on the ferry to reach the island; they run roughly every 30 minutes. Once on the island, you can get around on foot, golf cart, or scooter; the island is just 5 miles (8 kilometers) long.
The ferry to Isla Mujeres departs from Puerto Juarez, just outside Cancun, and arrives on the northern end of the island, within walking distance of local dive operators.
Peak season to visit the Cancun area is winter, when the weather is warm and dry. The Caribbean’s hurricane season runs from May through September, which is unpredictable but can mean rain and cloudy skies.
One of the most popular dive sites off Isla Mujeres is the Underwater Museum of Art (Museo Subacuático de Arte). Opened in 2010, the sculpture park is the work of artist Jason deCaires Taylor and was designed as a counterpoint to the effects of climate change on coral reefs. The sculptures will evolve as coral grows and the native marine life make the museum its home.
