Picnic Areas/Shelters

There is a picnic table at the parking lot at the Overlook and Sonoita Creek trailheads,  and several benches at scenic views along the trails. Check with staff for locations.

Equestrian Trails

Bring your own horse; no horses are for rent at the park. The Horse Corral Trail leads from a large parking area near Patagonia Lake and joins the Sonoita Creek trail which meets the New Mexico and Arizona Railroad Trail after the first creek crossing. Horses must stay on these designated sections. Other trails are not built to horse specifications and can be easily damaged by horse use. The Railroad Trail is a favorite of riders because it follows Sonoita Creek for almost five miles and is in shade in the summer months. Depending on the water level, there are three creek crossings. The Railroad Trail can also be accessed from Coatimundi Drive in Rio Rico. Check with staff for high water warnings and closures.
