Housed in what was once Cozumel's first luxury hotel, this museum has exhibits on the history and natural environment of the island. Displays on the ground floor explain Cozumel's ecosystems including the mangroves and coral reefs as well as local conservation issues. Upstairs, ancient artifacts found at local Mayan ruins are juxtaposed with relics of the Conquistadors. Native pottery and stone tools augment this historical exhibit. Another presentation on the second floor examines Cozumel's cultural and economic development throughout the 20th century. The museum also has the excellent Del Museo cafe. Guided tours are available.
