Pacheco State Park sits atop the Pacheco Pass in the Diablo Range, straddling the border of Merced and Santa Clara counties near Hollister. Spanning nearly 6,900 acres of rolling grasslands and oak-studded hills, this park rewards visitors with sweeping views of the San Luis Reservoir, the Santa Clara Valley, and on clear days, the distant Sierra Nevada.

Originally part of Rancho San Luis Gonzaga — one of California’s earliest Spanish land grants — the property was donated by Paula Fatjó, a descendant of the Pacheco family, ensuring its preservation. That ranching heritage is still visible in old corrals, stone walls, and the historic Fatjó homesite along the trail system.

The park is best known for its 28 miles of trails open to hikers, mountain bikers, and equestrians. The Spikes Peak Trail climbs to the park’s highest point for panoramic views, while the easier South Boundary Trail loops through wildflower-rich grasslands. Spring — mid-March through April — is the standout season, when the hills explode with lupine, poppies, and goldfields. Summers are brutally hot and bone-dry, so plan accordingly.

Birdwatchers will find raptors riding thermals above the ridgelines, and the open terrain makes wildlife spotting relatively easy — watch for coyotes, deer, and the occasional golden eagle.

With a 4.5-star rating across 306 reviews, Pacheco is a favorite among locals who appreciate its uncrowded trails and big views without the drive to the Sierra. It’s a genuine hidden gem in the Coast Range.
