Sunol Regional Wilderness, Regional park in Alameda County, California, United States.
Sunol Regional Wilderness is a nature reserve spanning about 6,859 acres with oak woodlands, grasslands, and dry shrubland along Alameda Creek in Northern California. The terrain features multiple trails and habitats supporting different plants and wildlife.
The area was protected in 1962 by the East Bay Regional Park District, transforming former ranch lands where Native Americans once processed acorns using bedrock mortars. Evidence of this historical use remains visible at several locations.
The visitor center displays a collection of more than 600 plant specimens and offers regular programs to help guests learn about local plants and animals. You can discover the variety of native flora and fauna firsthand.
The park is accessible by car with a parking area at the main entrance for visitors. Bring plenty of water since no supplies are available within the park, and allow time for walking the trails.
The reserve hosts one of the largest breeding populations of golden eagles in the region, actively hunting California ground squirrels across the grasslands. These birds of prey thrive here more than in many other California locations.
