Dublin Hills Regional Park is a regional open-space preserve in the eastern San Francisco Bay Area near Dublin, California, offering grassland ridgelines, oak woodlands, and chaparral habitat. The park provides a network of multiuse trails, scenic viewpoints of the San Francisco Bay, and links to adjacent open space that supports regional recreation, wildlife corridors, and watershed protection. It is managed as part of the East Bay Regional Park District system and is integral to broader landscape-scale conservation in Alameda County, California and Contra Costa County, California.
The park occupies upland ridges and valleys northeast of Dublin, California and northwest of Livermore, California, straddling municipal boundaries near Pleasanton, California and San Ramon, California. It lies within the northern reaches of the Diablo Range and offers views toward Mount Diablo, the San Francisco Bay Area skyline, and the Altamont Pass Wind Farm. The area provides habitat for species typical of East Bay ecosystems and serves as a recreational resource for residents of the Tri-Valley, California communities of Dublin, Pleasanton, Livermore, San Ramon, and Walnut Creek. The park’s corridors connect to regional trail networks used by hikers, equestrians, and trail runners from organizations such as the Bay Area Ridge Trail coalition and local chapters of the East Bay Mountain Biking Association.
The lands comprising the park were historically occupied by the Ohlone peoples prior to Spanish colonization, with later land use shaped by the Rancho San Francisco de las Llagas era and Mexican land grants. During the 19th and 20th centuries the hills supported ranching and grazing enterprises tied to families and entities in Alameda County, California and Contra Costa County, California. Land acquisitions for conservation and public access were facilitated by partnerships among the East Bay Regional Park District, state agencies such as the California State Coastal Conservancy, and local governments including the City of Dublin (California). Community groups and environmental organizations, including Save Mount Diablo and local land trusts, advocated for open-space protection culminating in phased park openings in the 2010s and 2020s. The park’s development intersected with regional planning efforts involving Measure WW (Alameda County)-style funding initiatives and state conservation programs.
Topographically, the park encompasses ridgelines, seasonal creeks, and north- and south-facing slopes typical of the eastern San Francisco Bay margin within the California Floristic Province. Vegetation communities include annual grassland, native California oak woodlands dominated by Quercus agrifolia and Quercus lobata, scrub and chaparral with species like Arctostaphylos (manzanita), and riparian corridors along ephemeral drainages feeding into the Alameda Creek watershed. Faunal assemblages reflect regional biodiversity: mammals such as coyotes, bobcats, and mule deer; raptors including red-tailed hawks and American kestrels; and amphibians and reptiles typical of East Bay habitats. The park lies within migratory pathways used by birds tracked by organizations like the Audubon Society and supports pollinators studied by academic institutions including University of California, Berkeley and California State University, East Bay.
Trailheads provide access to a network of multiuse routes supporting hiking, trail running, horseback riding, and limited mountain biking where designated. Notable alignments ascend to viewpoints offering panoramas of San Francisco, San Jose, and the Santa Cruz Mountains, and connect with the regional Bay Area Ridge Trail vision. Trails link to community trail systems in Dublin, California neighborhoods and offer loop options popular with organizations such as the American Hiking Society and local running clubs. Interpretive signage and volunteer-led guided walks have been organized in partnership with groups including California Native Plant Society chapters and local Boy Scouts of America troops.
Primary access points are located off arterial roads serving Dublin, California and nearby suburbs, with parking areas, trailhead kiosks, and rest facilities managed by the East Bay Regional Park District. Trail etiquette and multiuse user information are enforced consistent with EBRPD policies applied across preserves like Las Trampas Regional Wilderness and Black Diamond Mines Regional Preserve. Public transportation links from BART stations in Dublin/Pleasanton station and shuttle services during special events have been coordinated with regional transit agencies such as AC Transit and Livermore Amador Valley Transit Authority (Wheels). Accessibility improvements have been implemented following guidance from state agencies including the California Department of Parks and Recreation.
Park stewardship is led by the East Bay Regional Park District with technical support from conservation partners and volunteer organizations including Iron Horse Regional Trail advocacy groups and local land trusts. Management priorities include habitat restoration, invasive species control, erosion mitigation, and fire risk reduction consistent with plans produced by entities such as the California Department of Forestry and Fire Protection (Cal Fire) and regional fire districts. Monitoring and research partnerships with institutions like University of California, Davis and California Polytechnic State University, San Luis Obispo help inform adaptive management for species of concern and water-quality protection within the Alameda Creek and Arroyo Mocho subwatersheds. Funding mechanisms have included regional bond measures, grants from the California Wildlife Conservation Board, and local mitigation agreements tied to urban development.
Dublin Hills Regional Park functions within a matrix of protected lands and open-space preserves that includes Las Trampas Regional Wilderness, Vasco Caves Regional Preserve, Black Diamond Mines Regional Preserve, and city-managed parks in Dublin, California and Pleasanton, California. Connections to the Bay Area Ridge Trail and nearby ridgeline corridors enhance habitat connectivity for wide-ranging species and support recreational linkages to the Mount Diablo State Park and the Sunol Regional Wilderness. Collaborative landscape initiatives involving the East Bay Regional Park District, Save Mount Diablo, The Nature Conservancy, and regional planning agencies aim to maintain biological corridors across the Diablo Range foothills, promote climate resilience, and expand public access across the East Bay open-space network.
