Enchanted Rock is a geographical landmark 27 km (17 mi) north of Fredericksburg in Llano County. The rock is a huge, pink granite exfoliation dome that rises 425 ft (130 m) above the surrounding land, has a summit elevation of 1,825 ft (556 m) above sea level, and covers 640 acres (260 ha). Enchanted Rock offers 8.4 miles of hiking trails, camping, picnicking, rock climbing, and other outdoor activities. It is one of the largest batholiths (underground rock formation uncovered by erosion) in the United States, and was declared a National Natural Landmark in 1970. In 1994, the State of Texas opened it as Enchanted Rock State Natural Area after adding facilities. The same year, Enchanted Rock was added to the National Register of Historic Places.
