School Field Trips are on hold until ? (Why: The Volunteers of the Angeles National Forest, having provided fieldtrip opportunities at the Grassy Hollow Visitor Center for over a decade, were requested to move 2 miles east to the historical Big Pines Information Center. We moved our displays and since then have been open to serve the public on Saturdays and Sundays, and some holidays, from 10-4 pm. Unfortunately, the volunteers involved in running the school program are no longer with us. If you would be interested in rebuilding and adapting our fieldtrip program to the Big Pines setting, please join our membership!)
