The amazing Sidewinder Trail can be done as a loop, using nearby county roads that roughly parallel Sidewinder.

Need to Know

There are no legal cut-off roads between H75 and Ute Rd. (north half of this loop). It may be tempting to find a shorter route, but these trespass across private land. Please don't do this.


This is the legal route to make a loop from Sidewinder Trail, and also allows access to different segments of Sidewinder Trail. The suggested start is at Eagle Valley Trail trailhead.

From this trailhead, ride 1/4 mile back (west) to Peach Valley Rd. Go right, and follow Peach Valley Rd. north about 14.5 miles. Although there are a few short climbs at the start, it's a nice mostly downhill spin. Wear warm layers if it's cold. At 14.5 miles, take a right onto the paved 2200 Rd. Go about a mile, then take a right onto H75 (dirt).

It's only 3 miles to the north Sidewinder Trailhead, but this slightly uphill road might be the crux of the entire ride, at least psychologically. At the north Sidewinder Trail trailhead, shed your layers and get ready for 19 miles of technical singletrack bliss.

At the end of Sidewinder, continue on a short section of Sunset Rocks Trail to Eagle Valley Trail. This is a truly unique little canyon chute that narrows to a single bike width towards the bottom. The trail ends right where you parked.

From north to south, many roads connect to Sidewinder Trail: H75 Rd., Ute Rd., Dinosaur Rd., Duncan Rd., Bobcat, Wave Rd., and Eagle Road. All of these connect to the Peach Valley/2200 Rd. route to allow shorter loops.

Rode Sidewinder from North trailhead in early July - start early to get some morning shade! I rode the “half loop” - used Ute road to access the Peach Valley road to return to car. Next time will just ride out and back as Peach Valley road is a boring,dusty washboard ride. The trail itself is great - nicely technical, some steep sections, very well built. If you enjoy picking your way through techy rock sections, this is for you. At the middle section(near Ute road) it became multi use and quite sandy (due to Motos I would guess). My ride time for half loop was around 2.5 hours. Jul 10, 2018
