Climb to dramatic views on San Pablo Ridge, descend to wooded streamsides, and traverse open grasslands. This 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 gain and lose considerable elevation in short stretches: a 920-foot gain in Tilden Regional Park and a 600-foot loss in Robert Sibley Volcanic Regional Preserve. This long segment can also be completed in shorter sections.
Bikers prohibited on EBMUD section and some EBRPD sections.
Elevation Gain/Loss 1,785 feet/1,520 feet one-way (hikers and equestrians)
