Apollo 11 Model Aircraft Field is part of Woodley Park, on the western side of Woodley Ave. and north of Burbank Blvd. The L.A. City Woodley Park website has almost no information on Apollo Field, but driving directions are available. There is an access road, with a sign at the entrance - the red X on the map
The San Fernando Valley Flyers fly here. Check their website to learn about the group and see some great pictures.
