Sunol Regional Wilderness

Originally Ohlone territory, Sunol Regional Wilderness was a working ranch for over a century. Unlike a typical designated wilderness, cattle grazing continues on the land. However, outdoor recreation opportunities abound in this gorgeous spot that feels worlds away from the bustle of the East Bay. Comprising 6,858 acres, it was established as a park in 1962 and is administered by the East Bay Regional Park District.
