Parque El Molino is the local answer to Bustamante's dry heat: a shaded recreation park with pools, grills, and picnic areas fed by the town's spring water. On weekends it fills with families, music, food, and the easy chaos of a northern Mexican day out.
Come for a swim rather than solitude. If you want the natural side of Bustamante, combine El Molino with the Ojo de Agua canyon area; if you just need a cool break after the caves, this is the simplest place to linger.
