Sept. 15--? Upper Kurt's is closed.


Montrose isn't exactly known for all the great riding accessible from town, but this ride is "kind of" the exception, at least for fit riders. It features over 1,000 vertical feet of downhill singletrack over 10 miles. The views are some of the best anywhere! Canyons, red rocks, mountains, it's all there. The ride is doable as a 30-mile loop from town, or can be shuttled.

Note: If you ride this as mapped, there's quite a bit of road riding on both dirt and paved roads.

Need to Know

It can get pretty hot in the summer, so best to do this ride when the temp is below 80 or so.


Find Landfill Road northeast of Montrose. Ride the pavement until you almost reach the landfill gate, then head right on the dirt road. Follow the dirt road several miles up to Bostwick Park. Take a hard left at the sign that says "mountain bikes only". Follow the seldom traveled singletrack until you're back on BLM land.

Follow Kurt's Trail signs, then Skull and Crossbones Downhill. The singletrack is narrow and demanding. There are loose rocks here and there. When you reach a graded Elephant Skin Road, go left a little ways, and follow the "Z Ditch" sign. Follow Z-Ditch , a weird sunken arroyo with towering walls of Mancos shale. After several descents and climbs through other arroyos, find the Moonlight Mesa Trail sign. Follow this trail to the Mystery Ditch turn-off.

Mystery Ditch is fast and fun, not as deep an arroyo as Z-Ditch. All too soon Mystery Ditch ends and you're back on Chukar Road, a graded, graveled road. Follow Chukar Rd. downhill to Peach Valley Rd. and take a left. It's gravel for a few miles until you reach pavement again at Falcon Rd. Follow the paved 6400 Rd. back to town. It's about an hour spin to Montrose.

Great CX ride. beautiful views, a big climb, and varied terrain. Needs ridden more. Dec 11, 2016
Nice,stunning views, but Z-Ditch is a PITA - too narrow to pedal and not really interesting. Next time I'll bypass it. Mar 3, 2018
