Castle Rocks is a dramatic geological area of granite spires and monoliths similar to its larger neighbor, City of Rocks, to the north. The 1,440-acre Ranch Unit encompasses a portion of the rocks, as well as remnants of its ranching history, Indian pictographs, and superb recreational opportunities. This unit includes two picnic areas, miles of multiple-use trails, and excellent sport climbing routes. Castle Rocks State Park includes two other park units near Almo: Smoky Mountain (240-acres), and the Administrative Unit (12-acres). Smoky Mountain Unit offers 38 campsites (6 are open to equestrian campers), RV dump station, and equestrian trail head for the historic California Trail. The Administrative Unit includes the visitor center for Castle Rocks and City of Rocks, a picnic area, historic wagons exhibit, and park offices.
