About Sunol Wilderness Regional Preserve
Former ranchland near Sunol with hiking, horseback riding, and camping. Source
Bedrock mortars used by Native Americans for pounding acorns that were found in the area are reminders of Sunol's first inhabitants. For the past century, however, the land known today as Sunol Wilderness Regional Preserve was used almost exclusively as ranch land. Under the East Bay Regional Park District's multi-use land management policy, cattle continue to graze in the 6,859-acre wilderness.
