Jackson Flats in California. Ringed marker is this site; the other dots are the 1330 public campsites we map in California.
Jackson Flats is a group camping facility located next to beautiful Grassy Hollow Visitor Center, which holds numerous nature programs, hikes and activities on Saturdays during the summer. The peaceful setting, in the Angeles National Forest, is a short drive northeast of the bustling Los Angeles metropolitan area. Recreation Campers can enjoy hiking, biking and relaxing in the shade. A few short trails loop around the campground and a connector trail leads to the Pacific Crest Trail.
