Isla Mujeres, the Island of Women is an island about 8.1 mile off Cancun in Carribean Sea. Altough every year more tourists are traveling to this island, it still has retained its charm and tranquil atmosphere. As for Scuba divers main attraction is close encounters with Whale Sharks. The annual whale shark migration occurs from May 15th until September 15th near the waters of Isla Mujeres. But the peak time to visit is late July to early August. There are many tour operators but make sure to select the one own the boats. It gets very crowded where Whale Sharks are located late in the morning so look for tours that leave early in the morning.
Manchones Reef is another near by attraction. Its known for calm waters and lots of marine life.
