Dublin Hills Regional Park spans approximately 654 acres within an undeveloped open space corridor consisting of a main ridge that connects Donlon Point on the Park's southern boundary to Wiedemann Hill located on adjacent private property to the north, interspersed with steep-sloped canyons.
The parkland is bounded by Interstate 580 to the south, Schaefer Ranch to the southwest, private grazing land to the north, northeast and northwest, and California Highlands on the southeast.
The East Bay Regional Park's dog-friendly trails, including a segment of the Calaveras Ridge Regional Trail, provide local access and offer excellent views for hikers, bicyclists, and equestrians.
The Calaveras Ridge Trail begins near the Schaefer Ranch development and soon delivers you to grassland areas largely untouched since the 1800s.
