Boardwalk Section on the Missouri Research Park Trail

Highlight (Segment) • Trail

In total, the Missouri Research Park Trail is just under 5 miles long. There is a wooden bridge/boardwalk here next to the Missouri Bluffs golf course that is a pretty unique part of the trail.

Mononame 207 Reservoir

Highlight • Lake

The Mononame 207 Reservoir is a 22-acre lake off the side of the Busch Greenway. It's popular for fishing and has a pretty cool looking backdrop of trees. There's a spot with a bench on the north side of the lake where you can take a break and take in the view.

From tough singletrack to smooth double-track, the Weldon Spring Conservation Area has a variety of trails that are great for riding. Be aware: just because a trail has the word "Road" in the name doesn't mean that it's the easiest route!

Lost Valley Trail

Highlight (Segment) • Trail

This is what I was looking for. Narrow singletrack that runs along the terrain. Often off camber with lots of gravel sized rocks mixed in with clay and organic soils. The surface has great grip even when it’s damp. When the organic percentage rises it gives more and slips under climbing loads. The climbs aren’t too steep and there was always enough roots and rocks to keep you interested. Many stream crossings at the draws that were well prepared. Even the switchback were awesome with native stones packed in the clay to give you confidence you won’t wash out a wheel. Awesome. Be aware as of 2 May 2025 between the 5.5 and 7 mile markers there were many trees crossing the trail knocked over from a terrific wind or 🌪️. This is the area closest to the Army site.

Beaver Time

Highlight • Trail

Maybe the toughest single section of trail. There are two really excellent natural features to contend with and worth repeat attempts. Numerous lines. Careful of low siding if you stumble, could be very dangerous. S3

Matson Hill Park Trails

Highlight (Segment) • Trail

This 475 acre park is heavily forested and has a little over 7 miles of singletrack trails that roll through a large hollow. ;The old growth forest and steep terrain keep the area shady and dark along these challenging trails which can be ridden in either direction.

Highlight (Segment) • Trail

This trail runs alongside the Missouri River, providing a relaxing ride with the soothing sounds of the water. The trail is well-maintained dirt with ample tree coverage, offering pleasant shade along the way.
