Fodor's Expert Review Cenote Zací
A large, round, and beautiful sinkhole right in town, Cenote Zací—zací means "white hawk" in the Mayan language—is sometimes crowded with tourists and local boys clowning it up; at other times, it's deserted. Leaves from the tall old trees surrounding the sinkhole float on the surface, but the water itself is quite clean. If you're not up for a dip, visit the adjacent handicraft shop or have a bite at the popular, thatch-roof restaurant overlooking the water.
We recommend paying the extra MX$30 to rent a life vest here.
