Discover both the Yucatan capital of Merida and Dzibilchaltun—an ancient Mayan archeological site—on a shore excursion from your Progreso port of call. Begin with a sightseeing tour of Merida, the peninsula's cultural center. View the elegant 19th century mansions along its Paseo de Montejo and pay a visit to the Gran Museo del Mundo Maya—an artifact-filled museum dedicated to Mayan civilization. Next explore the Dzibilchaltun ruins and its intriguing Temple of the Dolls. You can even go for a swim onsite before returning to port.
