Cancún Underwater Museum
The collection at what is known locally as the Museo Subacuático de Arte (MUSA) consists of more than 400 lifelike statues that create marine-life habitats in three locations: off the shores of Punta Sam, Punta Nizuc, and Manchones Reef near Isla Mujeres. The sculptures at the Manchones site are 26 feet deep and best observed on a scuba dive. The two sites closer to Cancún, at half that depth or less, can easily be viewed on snorkeling or glass-bottom-boat excursions.
