San Juan Hill (elevation 1,781 feet), the highest point in Chino Hills State Park can be approached via the South Ridge Trail from either direction. The eastern approach, described here, originates from the Rolling M Ranch area of the park. Despite the $5 day use fee (the approach from Orange County is free) this is a good hike to keep in mind if you have already hiked San Juan Hill from the west or if you live in the Inland Empire. On clear days, the views are excellent, including Catalina Island, Mt. Wilson, San Gorgonio, San Jacinto and more.

Begin by heading south on the paved road, passing the eastern end of the Telegraph Canyon Trail (if you decide to do this hike as a loop, that will be your return route). In 0.2 mile, make a hard right on the South Ridge Trail. You climb almost 500 feet in the next mile, enjoying ever-increasing views for your efforts. At 1.6 miles from the ranch (1.4 miles from the start of the South Ridge Trail) you reach a Y-junction. Head left and begin the next major climb, picking up 500 feet in the next 0.9 mile.

At 2.5 miles from the start of the hike, you reach a junction on a shoulder just below San Juan Hill. Bear left on a service road (not the Old Edison Trail, which heads downhill) and almost immediately look for a use trail branching off to the right. Follow it a few hundred yards (it’s overgrown and narrow but not too difficult) to the top of San Juan Hill. Here you can enjoy a view of the Orange County coastal plain, San Juan Canyon, Telegraph Canyon, Mt. Baldy and more.

You can return via the same route, or if you prefer to make a loop, head down the west side of the peak via another use trail, rejoining the South Ridge Trail. Almost immediately, bear right on an unsigned, overgrown but easy to follow service road which drops down to meet the Bovinian Delights Trail. Follow the Bovinian Delights Trail to Four Corners, pick up the Telegraph Canyon Trail and head east for 2.5 miles back to Rolling M Ranch. This route adds about 0.8 mile and 100 feet of elevation gain.
