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.

Back to ride it in December 2025, all those trees were removed so it’s a lot more fun now. Most people seemed to ride the loop counter clockwise with the long gravel climb at the beginning. Clockwise was harder I think.

One of 3 major highway bridges over the Missouri between Weldon and St Charles, MO. The KATY trail through here is as smooth as concrete and the scenery is beautiful!
