When the city was just a Maya settlement it was called Zac?, which means "white hawk". But after the spanish conquered the city they called it Valladolid. One of the cenotes in the city is called Cenote Zac?. It is located at the intersection of calles 39 and 36, in a small park in the middle of town. You enter through a path that has been made in the roof and wall.
Located a few blocks east of the center of Valladolid is the beautiful cenote Zaci. You can climb down the stairs and visit this cenote which is open to the air one on side with the other side covered by stalactites with stalagmites below. A beautiful restaurant with a thatch roof is located at the site and it is open daily.
