The Devil’s Punchbowl is a unique 1,310-acre geological wonder where visitors can walk, hike or take a horseback ride on a 7.5-mile round-trip trail through a deep canyon formed by the runoff of large quantities of water from the higher San Gabriel Mountains. See spectacular up tilted rock formations created by layers of sedimentary rocks, or visit the Nature Center to learn about the native wildlife and park history. You can also explore the landscape of Joshua trees, California Junipers, Pinyon Pine Woodland and Desert Chaparral shrubs while observing the variety of wildlife.
