Dinosaur Valley State Park contains some of the best preserved dinosaur tracks in the World. The dinosaur tracks are located in the riverbed, so please call ahead to check on river conditions. There are two fiberglass models, a 70-foot Apatosaurus and a 45-foot Tyrannosaurus Rex. They were built, under commission of the Sinclair Oil Company, for New York World's Fair Dinosaur Exhibit of 1964 - 1965. Other activities include camping, picnicking, hiking, mountain biking, equestrian use in a separate 100-acre area, river swimming and fishing, and wildlife observation.
The South Primitive Area, a 100-acre section of the park, is set aside for equestrian recreation, and horses may be ridden only in this area of the park. Visitors must provide their own horses. There are no marked trails. A river runs through the area, and the terrain is wooded and semi-rocky. A parking area is provided for horse trailers; no potable water is available. River water is available for horses, but you must bring your own bucket. Restrooms without showers are located in the day-use park complex.
