Fodor's Expert Review Museo de la Isla de Cozumel

Filling two floors of a former hotel, Cozumel's museum has displays on natural history—the island's origins, endangered species, topography, and coral-reef ecology—as well as human history during the pre-Columbian and colonial periods. The photos of the island's transformation over the 20th and 21st centuries are especially fascinating, as is the exhibit of a typical Maya home. Guided tours are available.
