Overview

This is one of the more technical rides in the St. Louis area. There are many steep climbs and large rock gardens to test your skills. It is not for the faint of heart, you'll get a work out. This trail has been a pet project of GORC's (The Gateway Off Road Cyclists) for years now and they have taken it from the early days of less then 2 miles accessable to MTB riders to the entire park of just under 30 miles and growing!

Most riders start off at the Roundhouse parking lot and take Dogwood Trail toward DeClue trail. Dogwood is the easiest trail here to start off with and DeClue is the most technical. DeClue will lead you into Greenrock Trail and Eagle Valley Trail and back to Dogwood.

Bring your extra tubes with you to this park, it is notorious for cutting sidewalls with the rock spewn terrain. But don't let that deter you either. This is a blast of a park to ride and there is a lot of singletrack to explore!

Need to Know

Around the 7 mile mark there is a crazy steep rock garden called the monkey heads by the locals! Unless you are really skilled be prepared to hike-a-bike!

Description

This ride starts from the Roundhouse Memorial Parking lot. The trailhead is right off the lot. Head counter-clockwise on Dogwood from the trailhead for 3 miles of sweet hard pack flow. This first section is fast and fun, a great warm up for the techincal trail to come.

When you get to Allenton road is when the going gets more extreme. This is Declue trail, there is a smaller 8" log to hop just over the road and after the first few turns you'll get into the rock gardens. There are many rock gardens and outcroppings on this side of the trail to look forward to. At around the 7 mile mark you'll get to the monkey heads, a steep super rock garden to navigate. Only a few of the locals can ride up this trail so don't get discouraged!

After the monkey heads, things start to mellow out quite a bit and you'll come to a fork in the trail. There are two options here with the same destination. Take the new trail to the right - it's longer and more fun .

After you get to Scenic Loop road you'll stay left on Greenrock Trail singletrack and over to the visitors center. This is where I usually take a short break and have a snack and refill my hydration pack or bottles at the water spigot.

From the Visitors Center you'll head north on the Eagle Valley Trail. Around 1 mile in there's an 8% grade descent with switchbacks on loose gravel so take it easy. After that there are some nice climbs to get your heart rate up and legs burning, then you take a right onto Greenrock trail and head back down to the Roundhouse Memorial Parking lot where you started!

Flowing part of trail through scenic trees

Yes there were lots of rocky sections, but balanced out by lots of flow through these trees.
