Rising out of the chaparral-covered Gabilan Mountains, east of central California's Salinas Valley, are the spectacular remains of an ancient volcano. Massive monoliths, spires, sheer-walled canyons and talus passages define millions of years of erosion, faulting and tectonic plate movement. Within the park's boundaries lie 26,000 acres of diverse wildlands. The park is renowned for the beauty and variety of its spring wildflowers. A rich diversity of wildlife can be observed throughout the year.
The rock formations of Pinnacles National Park divide the park into East and West Districts which are connected by trails. More than 30 miles of trails access geological formations, spectacular vistas and wildland communities. The Pinnacles' rock formations are also a popular destination to challenge technical climbers.
On January 10th, 2013, President Obama signed legislation redesignating the area from national monument to full national park status.
