Location: At the convergence of Orange, Los Angeles, San Bernardino and Riverside counties, north and east of Yorba Linda.
Description: Chino Hills State Park preserves about 10,000 acres of unspoiled rolling hills in the middle of one of the fastest-growing areas in the country.
Activities: Trails and dirt roads in the park are popular with equestrians, hikers and mountain bicyclists (some trails are open to hikers only). Equestrian campsites offer water for horses, corrals, picnic tables and fire rings. Nature enthusiasts can enjoy a large protected stand of walnut trees, bird watching and spring wild flower displays.
Access: Automobiles can enter at only one point, through Bane Canyon in the northeast corner of the park (in San Bernardino County). Take California 71 north from the Riverside Freeway, then turn left on Pomona Rincon Road. After half a mile, watch for a brickyard and head west two miles on the adjacent dirt road.
