Park Entrance: Castleridge Trailhead
This beautiful 9090-acre parkland is on the oak-covered ridge overlooking Pleasanton and the Livermore Valley from the west. It is planned as the core of a Ridgelands Regional Park to be acquired over a period of many years. Parkland development has been intentionally limited to preserve the pastoral atmosphere.
The park occupies Pleasanton Ridge and beyond. To the northwest it spills down off Pleasanton Ridge into upper Kilkare Canyon, where it continues up onto Sunol Ridge, finally terminating at its westernmost corner in Stoneybrook Canyon. Inside the park, elevations exceed 1,600 feet. Listen to podcast.
To Reach The Park
There is one paved disabled parking and one wheelchair accessible portable toilet in the Foothill staging area. The two old redwood type drinking fountains would allow a wheelchair to get under but there is no smooth surface under these facilities. The park will install an upgraded fountain this summer for wheelchair users in an area by the disabled parking. There is one picnic table that can accommodate two wheelchairs and is also next to the disabled parking. The trails in the park are all multi-use dirt trails so they are more suitable for visitors who use electric wheelchair.
From the main staging area on Foothill Road you can follow a multi-purpose trail system, which accommodates hikers, equestrians, and bicyclists, provides canyon views and ridge-top vistas, and access to remote, deep-canyon streams.
