Alum Rock Park founded in 1872 was the first municipal park in the U.S. state of California. Located in a valley in the Diablo Range foothills on the east side of San Jose the 720 acre (2.9 km²) park offers 13 miles (21 km) of trails varying from fairly level along Penitencia Creek to sharp switchbacks climbing to the ridges to the South Rim Trail and the North Rim Trail.
