DzibilchaltúnIn recent decades Dzibilchaltún, once a busy port city, kept archaeologists busy with its 8,400 Mayan structures, including pyramids and remarkable vaulted architecture. The area’s most famous structure is the “Temple of the Seven Dolls,” named for the small clay figures uncovered there during archaeological work in the 1950s. Bring your bathing suit. The Xlakah cenote, a limestone sinkhole that kept archaeologists busy uncovering wooden tools and carved bones, is now a swimming hole to take the edge off of hot days. Bump up your experience by visiting at the vernal equinox when the compound lights up with an amazing show put on by Mother Nature. The event draws plenty of new-age enthusiasts and photographers.
