The information about Bailey Canyon Park has been placed in the Guide to the Trails of Bailey Canyon. That page contains the history of the Park, as well of the entire Canyon, and a detailed guide to the trails accessed from the Park, complete with topo maps.
Sierra Madre's Bailey Canyon Park is an excellent page from the Sierra Madre News Net which contains pictures of the trailhead sign, picnic tables, fire ring, and the interpretive display at the Park.
