The dream of riding down the Cajon Pass is a reality! A fun downhill route to McDonalds!

Ever thought about biking down those huge Cajon Pass mountains as your riding up the Cajon Pass going north on the 15 Freeway to Victorville or Las Vegas? Grab your mountain bike and make it a reality. It's fun and the majority of it is all downhill. Takes about maybe 2 hours. Because the majority of the route is downhill and on maintained fire roads, you don't need to be a pro to ride this. You always have the option to climb up this same route.

You can start on on Oak Hills Road that's conveniently located off of the 15 Freeway. Finding parking in this area is no problem. If you start here, you'll ride through a small Oak Hills neighborhood, but you'll soon get on the Forest Route #3N21 fire road. A short climb up will begin the long descent to Highway 138. Very fun and one will enjoy the views while riding down.

Forest Route #3N21 will join with Baldy Mesa road which will take you under the freeways and will turn into Santa Fe Road. Continue on Santa Fe Road to Highway 138. After passing Highway 138, the long descent will turn into a paved road and will take you to McDonalds. Enjoy!

Even though we did map this route end point to McDonalds, you do have the option to continue the ride on Old Route 66 also known as Old Cleghorn Road to the Fontana train station off of Sierra and take a bus back to the Oak Hills area. They do allow bikes on the bus that runs every other hour.

If you plan to continue, pass the McDonalds until the road ends and take the left trailhead that forks off. Take the right trail from the fork and go underneath the freeway. The left trail is the PCT known as the Pacific Crest Trail. You can't ride your bike on the PCT. As soon as you pass the freeway, take the trail on your left and it will join the Old Cleghorn Road. You have the option to ride that Cleghorn to Sierra Road or take the trails between which all goes and ends in the same direction that Old Cleghorn Road take you to.
