Diablo Foothills Regional Park Trailhead Parking

Pine Canyon, which includes the Castle Rock EBRPD recreational area and the Diablo Foothills Regional Park just beyond, provides rich habitat and resources for spring migrants passing through, as well as for many returning and nesting summer residents. Warbling Vireos along with their cousins, the Cassin’s Vireo, nest within the canyon. We can also hope to find orioles, flycatchers and wrens, various warblers, and if we're lucky a Lazuli Bunting or Peregrine Falcon.Bring water and snacks, and lunch, if you'd like to take advantage after the trip of the shady picnic tables in the park.Trail Rating: Category 2–3. Out-and-back along a wide dirt trail, with some short climbs. We'll need to cross little Pine Creek several times---without bridges. These crossings are not deep but can be muddy or a bit adventuresome, depending on recent rains.Elevation change: 200 feet, in a gradual climb.Leader: Ted Robertson, 925-899-1872Meet: Diablo Foothills Regional Park trailhead parking lotDirections: From Ygnacio Valley Road, drive south on either Walnut Avenue or Oak Grove Road to the traffic circle.
