This is a great route that mixes a fair amount of quality climbing and takes advantage of the best singletrack riding Chino has to offer.

It would be even better if the west entrance of North Ridge was open. To get around the closure, this ride heads up Telegraph Canyon and hooks up with North Ridge via Sycamore Trail.

Singletrack highlights include McDermont Singletrack, Raptor Ridge, Faultline Trail, Aliso Canyon Trail, Bane Ridge Trail, and Bovinian Delight Trail.


This ride starts at the Rim Crest entrance but could also be started from Carbon Canyon Park or even the east ranger station entrance. From Rim Crest, get onto South Ridge and head west (left) up a steep but short climb towards the glider station. Past the glider station, kick it into a bigger gear and enjoy the fast roll-overs to Telegraph Canyon.

Head east on Telegraph Canyon up the canyon a few miles and keep an eye out for the Sycamore Trail signpost. Turn left onto Sycamore Trail and settle in to a steady, sometimes steep, climb up to North Ridge.

Turn right onto North Ridge and follow it all the way to the top of McDermont Singletrack. Take this high-speed singletrack down to Telegraph Canyon and turn left to get to Four Corners.

From Four Corners, take Raptor Ridge, until it turns into a fire road (after a short climb) and continue down 100 yards until you come to a singletrack entrance on the left, which is Faultline Trail. Faultline Trail is a great, high-speed, toboggan-run like singletrack that drops into a fire road, just short of the east ranger station.

Once on the fire road, watch for a quick left (and take it) onto another fire road that turns into Aliso Canyon Trail. Plan for some good singletrack climbing that meanders up until you get to a "T" intersection at Sidewinder Trail.

Turn left onto Sidewinder Trail and ride until you come to another "T." Turn right and enjoy the amazing Bane Ridge Trail, which is a mix of semi-technical drops, sweeping turns, and high-speed, downhill sections before dumping you into the Equestrian Staging Area.

Once in the open staging area, make a quick right and look for the Equestrian Center Connector singletrack, which connects the equestrian center with the main road to the ranger station.

Turn left on the main (paved) road, make another left at the "T," and work your way to the South Ridge fire road entrance on the right, and climb your way to Telegraph Spur, and turn right to get you back to Four Corners.

To finish this ride, take the Bovinian Delight Trail from Four Corners back onto South Ridge and head west back to Rim Crest.
