California is home to many unforgettable natural wonders, but one of its most underrated destinations is Pinnacles National Park, a striking rocky landscape shaped by ancient volcanic activity. Visitors can explore more than 30 miles of trails through the complex terrain, including mysterious caves and soaring rock walls.
Despite its compelling landscapes, Pinnacles remains one of California’s smaller and less-visited national parks, welcoming about 354,076 visitors in 2024, according to the National Park Service. It was second only to the remote Channel Islands National Park, which had 262,581.
Compared with heavily visited parks like Yosemite, which draw over 4 million people each year, these quieter parks offer a refreshing alternative during the busy season. Here’s a closer look at Pinnacles, which you can reach in just over 2 hours by car from SF.
Geology of Pinnacles National Park
The dramatic landscape at Pinnacles formed through millions of years of tectonic activity where several of Earth’s plates meet. When the North American plate moved over the heavier Farallon plate around 60 million years ago, the Farallon plate subducted and eventually melted, pushing magma up toward the surface.
The resulting volcanic eruptions built the Pinnacles about 22-23 million years ago, and further erosion shaped the area as we know it today.
Visiting the Pinnacles
Popular Pinnacles hiking routes include the easy Prewett Point Trail, the moderate Old Pinnacles Trail to Balconies Cave, and the challenging Chalone Peak Trail. Rock climbing is also available, but can be risky due to the park’s fragile rock. Experienced climbers tackle rocks along Machete Ridge, including top-ropes and multi-pitch climbs.
Keep an eye out for endangered California condors and turkey vultures, which are among the 181 recorded bird species known to soar high above the peaks.
Visitors can stay overnight at the Pinnacles Campground, which accommodates both RVs and tents and provides amenities such as picnic tables, showers, and a seasonal swimming pool.
