Though San Juan Hill’s height of 1,781 feet might seem minuscule by California standards, there is no higher point between it and the ocean or downtown L.A., meaning that on clear days, views are excellent. The peak is the highest in Chino Hills State Park and can be reached from the east or, as described below, from Yorba Linda’s Rimcrest trail head.
From Rim Crest, pick up the South Ridge Trail and head east, immediately making a stiff climb, picking up 200 feet in the first 0.3 mile. The trail soon levels out and continues to follow the ridge, providing views of north Orange County and the Santa Anas to the right and Telegraph Canyon and Gilman Peak to the left. You pass junctions with the Little Canyon Trail (0.9 miles), two service spurs (1.4 and 2 miles) and the Bovinian Delights Trail (2.5 miles.) Just after you cross an unnamed service road, look for a use trail signed for San Juan Hill. A short climb brings you to the summit where your efforts are rewarded with a 360-degree view. Mt. Baldy dominates the landscape to the north, towering above the Inland Empire suburbs. In the other direction, on days of good visibility you will be able to see the Palos Verdes Peninsula, Catalina Island and the Santa Monica Bay.
If you have time for a slightly longer return, an enjoyable option (especially on warm days) is to return via shaded Telegraph Canyon. To do this, follow the wide service road to the Bovinian Delights Trail, a single-track which leads you to Four Corners. Head west on the Telegraph Canyon trail which soon enters an attractive oak woodland. At 2.8 miles from Four Corners, pick up the Easy Street Trail and follow it uphill, half a mile back to the trail head. This variation adds 1.1 miles and about 100 feet of elevation gain.
