This is one of the go to trails in the St. Louis area. It is ever expanding with the volunteer help provided by GORC. Enjoy the Technical and flowy trail with short stints of doubletrack gravel.

Bring your Bug spray in the late spring and summer!

Need to Know

Stay light on your feet and off the saddle in the rocks to prevent flats, but bring items to repair them also!!!


Head down the fire road into the property to get to the singletrack. Where the doubletrack opens up to the right head that direction, then to the left toward the middle climb.

Just to your left after turning onto the middle climb, you'll see the opening for the singletrack. This is the newest section called the beaver pond section. It is by far the most technical section of the entire trail with only 8" to 10" tread and some rough terain. You'll round the beaver pond just after clearing an armored drainage crossing and get back onto a shot stretch of fireroad.

At around the 2.5 mile mark, you'll see singletrack peel off to the right. This is the root ball section and with a good climb to start off and a couple tight swithchbacks. it will lead into a long climb into the "Cedars" and accross a spring crossing into the Haunted Hollow.

From there you just go with the flow of the trail for the next 3 miles. A little before the 6 mile mark (from the start of the ride)you'll hang a left and climb up to the top of the back fire road. There is a long fairly straight descent, but be careful. The gravel is very loose and prone to ruts so you can get caught off guard pretty easily.

At 7.5 miles hang a right to stay on the trail, from here you'll cross the same creek 3 time before getting back in to singletrack. This section is a fast flowy section in an oak hickory forest. A little after the 9 mile mark you can head right to take another lap and make it a 20 mile ride or you can keep straight and turn left to head back up the fire road to the main trailhead parking lot. I usualy take two laps if the weather is nice!
