Mountain Biking Lost Valley

The Lost Valley Trail in Weldon Spring Wildlife Area is a perfect ride for beginners. Eight miles long, is uses abandoned farm roads that later served as access to local ammunition stockpiles during World War II. These roads vary from double-tracks still used by Conservation Department patrols to abandoned paths through the woods. With the exception of a couple of washed-out places, the hard-packed trail now known as Lost Valley Trail can be handled by novices. Riding the loop in a clockwise direction will make your climbs easier and your trail markings more visible. This trail is located in the Weldon Spring Wildlife Area, 30 miles west of St. Louis.

Rider questions

Q: Is there a certain time it opens?
A: LV is managed by the MO Dept of Conservation and is open year round. During managed hunt season, it is still accessible as hunters are restricted from a certain distance of the trail but riding later in the morning during hunt season is probably wise. Also, trails are open every night but not after 11pm. Lower trailhead is a gravel lot approx. 6 miles from Hwy 40/61 & 94 intersection but more popular is "the Mound" parking lot, adjacent to the Weldon Spring Interpretive Center, only a couple miles from the Hwy 40/61/94 intersection and accessible via the Hamburg Trail before dropping in to LV. Mound parking is nice for night rides because of the lighting.
