If you find yourself stuck in traffic on the 91 Freeway, the hike through Fresno Canyon and the ridges above it make for a nice place to stop and stretch your legs. Thanks to the Inland Empire hiking group “Lazy Ass Hikers” the trail has been recognized by the city of Corona. This post describes a moderate hike that can be knocked out in a couple of hours but one doesn’t have to do the entire route to get a good workout and good views. Conversely, hikers who want more of a challenge can continue farther up the ridge.
From the corner of Nicholas Place and Green River Road, head west on Green River Road to the signed trailhead. The first 0.7 mile is fairly uneventful but after you cross Oakridge Drive, the incline increases significantly. Half a mile of rigorous climbing brings you to a T-junction. The left fork leads to a small knoll with views; this is a good destination for hikers short on time or with small kids. The right fork, now an unofficial but easy to follow single-track, climbs steadily uphill along the ridge. The terrain is loose in spots and tends to erode after rain so exercise caution.
At 1.7 miles from the start, you reach a knoll that can be climbed either by a steep fire break or by continuing along a single track which intersects a service road. From the knoll, you can enjoy a 180-degree view of the Santa Ana Canyon, Chino Hills, San Gabriel Mountains, San Gorgonio and San Jacinto. This is a good turnaround point, but if you’re up for an even steeper climb, you can continue along the ridge to Leonard Road – 1.5 miles and 1,500 feet higher.
