Cal Orkco is a collection of dinosaur footprints impressioned on a 70 degree wall of a cement quarry, which used to be a lake floor. To visit it take the Dino Truck at 9:30AM, 12:00AM or 2:30PM from the corner of Plaza 25 de Mayo. The guided visit takes about 2 hours and cost 30 Bs. Note that you won't be able to see the dinosaur footprints up close; instead, there's a viewing platform with binoculars (and some "full size" fibreglass models of dinosaurs).
