“Best route in Chino Hills State Park; burly ascent, miles of fast and flowy downhill singletrack!”— Rob Moore
Family Friendly Campgrounds, historical buildings, amphitheater, and Ranger Station.
An alternative start point for this loop can be accessed from Gas Company Road at the southwest corner of the park. To get to Gas Company Road, there is a horse trail right after Hollow Ridge Ct, that is off of Casino Ridge Road. You can either park in the parking lot near the bottom of Casino Ridge Rd or, if you have someone dropping you off, you can drive all the way up Casino Ridge to the end and jump the fence to bypass the horse trail. Do not leave your car parked at the end of Casino Ridge.
A good alternative endpoint is down Lower Aliso Trail off of the Rolling M Ranch Singletrack. This takes you to the Santa Ana River Trail - Green River Golf Club to Prado Dam or the Alluvial Trail, which can both be used to head south toward the parking area for the Santa Ana River Trail off Hwy 91.
Bane Ridge Trail drops you out onto Bane Ridge Rd. Turn right and head downhill toward Rolling M Ranch. Hook a left after a short descent, pass up and around the gate, and begin the burly fire road climb section on South Ridge. After a 1.25-mile ascent, the road veers right, but stay left for the 14% grade up San Juan Hill, the tallest point of the park. At the top, take a breather and check out the spectacular 360-degree view!
This is where the fun begins, again! Get ready for a fast and furious drop down South Ridge Rd. to Bovinian Delight Trail. The trail is signed, but you'll have to brake fast to make the hard right turn. Continue down Bovinian Delight Trail for more undulating singletrack fun. Be mindful as there are more people (hikers, bikers, and equestrians) ascending the trail, than descending. At the bottom, stop and take a break at four corners, or blow through, staying to the right to begin an easy ascent up Raptor Ridge. Raptor Ridge is the only singletrack option at four corners, and it is signed.
After a short distance, you'll quickly encounter the only true technical bit of the ride. Its a hard left, up and over an outcropping of jagged rock.
Continue on to the power tower and begin another short descent down a short doubletrack, keeping in mind you'll want to be prepared for a quick and hard left. This trail is the aptly-named Faultline Trail (signed), as it parallels the Yorba Linda tangent/spur section of the bigger, Yorba Linda fault line. You can see where the ground has heaved and slid, and this fast, and often off-camber section, runs right through it. Be careful because you'll hit high speed at the bottom of Faultline Trail, and the trail veers quickly to the left before dropping you out on Upper Aliso Canyon Trail doubletrack. Stay right and take this trail down to the Rolling M Ranch.
Veer left once you pass the buildings and amphitheater, staying on the dirt section that parallels the paved road. Again, you'll have a hard left where you'll cross a bridge and head up what Strava refers to as 'Young Magicness.' This trail will drop you out at the equestrian staging area. Stay left and start up Bane Ridge Trail. Shortly after beginning this ascent, keep right at the fork onto the Spur Connector, which is just that, a short spur of singletrack that will dump you back onto Bane Canyon Rd. From here, turn right on the paved road and finish up at the Lower Aliso trailhead.
Extra Credit: Upon completion, I like to repeat the beginning of the ride: up Bane Ridge Rd., down Bane Ridge Trail.
Another great option is to continue south past the trailhead where you started, and take Telegraph Canyon Rd (left through gate) to Edison Rd (first right). You can climb this doubletrack, then blow back down Faultline Trail/Upper Aliso Canyon Trail.
Both options add a few extra miles, offer good climbs, and top off your day with barreling, downhill singletrack!
Once the Europeans arrived and founded Mission San Gabriel in 1771, the Chino Hills were used extensively for grazing by mission cattle. During the Mexican Republic, the park was also utilized for grazing by surrounding Mexican ranchos Santa Ana Del Chino and La Sierra Yorba. Cattle-use continued until 1984 when State Parks and Recreation finally officially declared the area a part of the state park system.
Today, CHSP is considered a premier natural open space containing over sixty miles of fire roads and trails. The Parks 14,100 acres contain prime real estate from the counties of Los Angeles, San Bernardino, Riverside and Orange. Additionally, the area provides an anchor parcel for the Puente Hills Wildlife Corridor.
