The Arroyo Pescadero area of the Preserve is the site of a former oil field and features several oil company roads that are now used as recreational trails. The relatively level, 2-mile Bob Henderson loop trail is a popular option and perfect for families. Several habitat restoration projects have been completed along the Arroyo San Miguel Trail (east of Colima Road) providing lush expanses of native Coastal Sage Scrub habitat for various species of sensitive wildlife, including the federally threatened coastal California gnatcatcher.
The trail network can be accessed via the Arroyo Pescadero Trailhead on Colima Road in Whittier. The gated trailhead provides a restroom, onsite parking, Americans with Disabilities Act (ADA) access, drinking fountain, and equestrian staging for trail users. Near the trailhead, educational kiosks can be found along a short ADA-friendly decomposed granite trail surrounded by restored habitat. Nearby, a rammed-earthen amphitheater at a scenic vista offers a rest area for hikers. Because of the presence of ecologically sensitive resources, dogs are not allowed on Arroyo San Miguel Trail. Bicycles are not allowed on Bob Henderson Loop Trail or the adjoining Deer Loop Trail. A printable map of trails in the area, and their allowable uses, is available here.
