Santa Ana Mountains & Chino Hills State Park (Folded)
Side 1 shows the Forest Service Roads trails and singletrack of the Santa Ana Mountains (the Trabuco District of the Cleveland National Forest. It covers from the edge of Chino Hills State Park to Lake Elsinore & includes a detailed map of Whiting Ranch Wilderness Park & O'Neill Regional Park. Roads & freeways show routes to the trailheads of the Santa Anas.
Side 2 shows Chino Hills State Park in shaded relief with fireroads & singletrack throughout the park. Back in 1992 when I started mountain biking at Chino Hills there was no map of the State Park - so I drew my own. The same applies to the Santa Ana Mountains.
