Vasquez Rocks Park, Natural rock formations in Agua Dulce, California.

Vasquez Rocks is a 932-acre park with tilted sandstone formations rising from the ground at 45-degree angles and reaching heights of about 150 feet (45 m). The park offers marked hiking trails, a nature center, and equestrian areas accessible daily from sunrise to sunset.

The Tataviam people lived here before Spanish and Mexican settlement, and the rocks later took their name from Tiburcio Vasquez, a bandit born in 1835 who used the formations as a hideout. In 1972 the site became a Los Angeles County park, and the 932 acres were later designated a National Historic Landmark for their geology.

The tilted sandstone slabs have appeared in hundreds of productions since the early 20th century, including Westerns and the 1960s Star Trek episode "Arena", where Captain Kirk fights the Gorn. Fans still walk to the spot used for that scene.

The park is open year-round from sunrise to sunset with parking facilities for those planning to hike or ride. Bring plenty of water since shade is minimal and temperatures can rise significantly during the day.

The famous Pacific Crest Trail, running from Mexico to Canada, passes directly through the park past the characteristic rock formations. Hikers on this legendary route experience this section as one of many highlights on their journey.
