Cenote Zací is a hidden natural treasure in the heart of colonial Valladolid. This semi-open limestone cave features turquoise crystal-clear water surrounded by towering rock walls draped with hanging tropical vegetation. Sacred to the ancient Maya, its name means 'White Hawk' in the Mayan language. Visitors can swim in the cool freshwater and admire the cave from wooden platforms. An on-site restaurant overlooks the cenote, with changing rooms and showers available for swimmers.
