Pine Canyon, which encompasses the Castle Rock (EBRPD) recreation area and Diablo Foothills Regional Park, provides rich habitat for spring migrants and returning summer residents. Warbling Vireos and their cousins, Cassin’s Vireos, both nest within the canyon. We also hope to find orioles, flycatchers, wrens, and various warblers—and if we’re lucky, a Lazuli Bunting or a Peregrine Falcon.

Please bring water, snacks, and a lunch if you would like to enjoy the shady picnic tables in the park after our trek.

Trail Rating: 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 very gradual climb
