National Park Service, California.
Some 23 million years ago multiple volcanoes erupted, flowed, and slid to form what would become Pinnacles National Park. What remains is a unique landscape. Travelers journey through chaparral, oak woodlands, and canyon bottoms. Hikers enter rare talus caves and emerge to towering rock spires teeming with life: prairie and peregrine falcons, golden eagles, and the inspiring California condor.
Pinnacles National Park is accessible through highway 101 for the West entrance, and highway 25 for the East entrance. From highway 101 you must pass through the City of Soledad to find highway 146 which will lead to West side of Pinnacles. To enter East Pinnacles you must find highway 25 through the City of Hollister coming from the North, and King City through Bitter Water Road (G-13) when coming from the South. NOTE: There is no through road between the east and west entrance.
