It is a unique place due to its characteristics and attractions. Its name comes from the shape of a water reservoir built in 1730. This important hydraulic work, 7 meters deep, is still preserved, and when you visit it, you can transport yourself to the colonial era.

There are over 40 replicas of animals from the geological eras of the Miocene and Pleistocene in life-size. You can take a ride on the mini train or visit the small islands that have become a refuge for migratory birds and take a boat ride on El Cedazo dam.
