County: Contra Costa
Difficulty: Moderate to Strenuous
Climb to dramatic views from San Pablo Ridge, descend to wooded streamsides, and traverse open grasslands. This challenging trip along the spine of the East Bay Hills crosses varied landscapes on trails that range from wide and rocky service roads to duff-covered narrow paths. You’ll find sheltered, tree-covered sections and exposed, breezy segments, and often encounter fog. You’ll gain and lose considerable elevation in short stretches–an 860-foot gain in Tilden Regional Park and a 600-foot loss in Robert Sibley Volcanic Regional Preserve.
Make it longer: Join us for our annual East Bay Hills Hike and Ride and thru-hike for 1 to 5 days. Your choice!
Make it a loop: Create a smaller loop at either end of this trail with Tilden or Sibley’s many trails.
