Sunol Regional Wilderness

Sunol Regional Wilderness is located in Alameda County, California, occupying over 6,300 acres of rolling hills, grasslands, oak woodlands, and riparian corridors. Managed by the East Bay Regional Park District, the area preserves a natural landscape that supports a wide variety of wildlife, including deer, coyotes, bobcats, and many bird species. The park’s rugged terrain features steep hills and valleys carved by Alameda Creek, the largest watershed in the East Bay. Historically, the land was home to the Ohlone people and later became cattle ranching property before its transformation into protected parkland. Visitors can explore over 37 miles of multi-use trails, which wind through oak-studded ridges and along streams, offering panoramic vistas of the Diablo Range and nearby urban centers. Key landmarks include the Quarry Rock viewpoint and the historic Roberts Regional Recreation Area. The park’s varied habitats make it ideal for hiking, mountain biking, horseback riding, bird watching, and photography. Sunol Regional Wilderness also plays a role in regional conservation efforts, providing habitat for sensitive species and protecting watershed health. Its proximity to the Bay Area and relatively undeveloped character make it a popular destination for families, trail runners, and nature lovers who appreciate a quiet outdoor experience within reach of the city.
