Pinnacles
Around 23 million years ago, a series of volcanic eruptions shaped the landscape that is now Pinnacles National Park. The remnants of these ancient eruptions have formed a striking terrain of rocky spires and deep canyons. Visitors can explore diverse environments, from chaparral and oak woodlands to the cool, shaded depths of canyon floors.
