Trail shared by Katie Oswald

A fun, but challenging loop starting at the Miller Parking lot going counter clockwise.

The trail running along the creek may flood after heavy rains.


A fun, challenging, and scenic loop. The climbing is mostly a jeep road (Carr Rd), but the downhill and singletrack are techy fun!

Need to Know

There is no water available along the route and the whole course is exposed to sun, so bring plenty of water.


Park at the lower Miller Peak lot and start out on Perimeter Trail to Carr Rd. Head left on Carr Rd (go up) for a little under 2 miles. When you see the "S-turns next two miles" sign, you know you're really close. Make a left onto Clark Spring Trail #124 and follow this until the trail makes a really hard left and heads down the mountain a little. Keep an eye out as the turn can be tough to see. it is the first marked trail you'll see.

From here, you'll go through some fun S turns, follow the ridge, and make another hard left onto Lower Miller Canyon Trail. It is the only other marked trail off Cooper and will shoot you out into the upper Miller Parking lot.

From here, you can head down the road to the lower Miller lot or head straight across the parking lot and drop into Lower Miller Canyon Trail (not really marked). It weaves along the creek, crosses it once, and will end at a gate. Go left and it will pop out onto the road past where you parked. When you hit the road, make a left and head back up to the parking lot.

First few miles from Miller canyon to Carr road are very difficult. Rocky/technical and narrow. After that, it is a fun ride. Best part was the Miller 10mi

A lot of the trail is pretty rocky but fun in a challenging/techy way. Missed the very bottom part of the Canyon trail and finished on the road 9.2mi
