A fire road climb leads to awesome technical downhill.

Super fun rock features on Mt. Hillyer make the fire road climb worth it.


Starting at the southernmost point in the loop, head north-west on 3N14. You'll take this road past parking lots, past a fire station, then it turns to dirt and you'll keep going. The climb is very gradual so you can blast through this section. Keep going until you'll all the way around to the North side of Hillyer, Alder saddle, where you meet another paved road. Take a right here, head up a little ways and take the first trail you see on the right.

This trail climbs through a burned-out section, watch out for the Poodle-Dog bush, then steepens to climb a stupidly-steep wall. After this, it gets good. You roll through a meadow and quickly reach the highest point. The downhill into Horse flats campground is high quality fun: fast and flowy sections mix with technical rock features to keep you our of your saddle and smiling. Watch out for hikers and the rock climbers as some bouldering problems are right next to the trail.

Too soon, you'll reach the campground and the junction with Silver Moccasin trail. Take Silver Moccasin south which is another quality section, with flow around bermed corners, tight switchbacks, and lots of waterbar steps.

You'll come out onto 3N21, which you can immediately turn right and do the loop again, or continue on Silver Moccasin another mile or so to 3N14, where you started.

History & Background

Some sections have significant damage from station fire, watch out for fallen burned out trees and poodle-dog bush.

Much of the "wall" was much to steep for me to ride, but short so no problem walking a few 100 feet a few times. Likewise the ride down has a few spots to scary for me (63 y.o. grandpa) so I walked those and thoroughly enjoyed the rest of the ride. Beautiful area especially in the spring, and lots of fun rocks to ride down. Well worth the drive. Probably nice in the summer too when temps reach the 100's down here. I had a hard time finding the start of the ride (3N14), consult the map carefully if not familiar with this area. Jun 11, 2016

Did this run yesterday. The final piece of the uphill (the "wall") is a tough section and I walked a bit of it. There is definitely some big hitting technical sections on the way down, but lots of fun. Aug 19, 2018
