Trail shared by Dave Reed

A great way to blend some newly built trail with an iconic old one.

There's tremendous off-road riding available outside the town of Fairfax, but as a true testament to your mountain bike prowess you owe it to yourself to ride Repack Road at least once before you die. This offers a pretty good amount of singletrack riding in order to get to the top of the trail, along with some doubletrack fireroad with plenty of climbing. Also it gives you a chance to pop into the iconic new flow trail on your way out there.

Need to Know

Be sure to get a day/season pass for the Tamarancho trail system from one of the shops in town before starting.


From Fairfax, ascend through the city streets following the signs towards the Tamarancho trail system, be sure to also pick up a day pass at one of the local shops. Ascend along the roads until you hit the trail loop and then start the ascent in the clockwise direction. Start with Alchemist Trail, turn left onto Goldman Trail, right on Serpentine Trail, and straight onto B-17 Trail. Essentially, keep following the main singletrack out until you top out near the flow trail. If it's open and you want to take a few quick hot laps on the flowy stuff, feel free.

Ascend out of the loop and onto the White Hill Fire Road. Ascend this until it intersects with San Geronimo Ridge Road and take a left. Follow the road out until you see a sign saying "Cascade Canyon Road (AKA Repack)". This is your descent. Follow this fast trail all the way back down to Fairfax. And enjoy the creek crossings!

History & Background

There's a tremendous amount of history surrounding the Repack trail, starting with Charlie Kelly's webpage:…

Also, there's a new mountain bike museum slated to open in Fairfax that you should absolutely check out at the end of your ride!

If you don't enjoy climbing and switchbacks, this is not the trail for you. That said, views are amazing and the Repack Road downhill is a total gi… 14.8mi
