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 Regional Wilderness 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.
The Dirty Dare Trail Run was designed by Catra Corbett to give you a
taste of all the beauty and splendor Sunol has to offer. You’ll start
you run with amazing views of the park, Alameda Creek watershed and
Calaveras Reservoir. Once you have made it up to the Macquire’s Peak
Loop you’ll be greeted with oak woodland and grassland communities,
fossiliferous sandstone outcrops and excellent views of San Antonio
Reservoir and Mt. Diablo. The Eagle Peak trail leads you through the
“Valley of the Giants” while providing excellent views of the park,
Calaveras Reservoir and south bay areas. As you reach the south end of
the park you are greeted by chapparal, oak woodland and grassland
communities that provides a gently rolling route back to the finish
