Pinnacles National Park is an American national park protecting a mountainous area located east of the Salinas Valley in Central California, about east of Soledad and southeast of San Jose. The park's namesakes are the eroded leftovers of the western half of an extinct volcano that has moved from its original location on the San Andreas Fault, embedded in a portion of the California Pacific Coast Ranges. Pinnacles is managed by the National Park Service and the majority of the park is protected as wilderness.
