Lon Sanders Canyon Conservation Area is about two and a quarter hours southwest of St. Louis, just outside Piedmont, and it rewards the drive with a compact version of the Ozarks at their most atmospheric.
The hike is short — the canyon trail is just under a mile — but packs in stone bluffs, shut-in waterfalls on McKenzie Creek, and hand-cut stone steps built into the rock faces that suggest serious historical effort. The canyon is a rocky gorge carved through the surrounding highlands, and the geology has the characteristic Ozark quality of layered limestone with occasional volcanic intrusions. The waterfalls are modest but real — water dropping over rock shelves into small pools, the sound amplified by the canyon walls.
The conservation area carries a historical rumor: the Jesse James gang allegedly used this canyon as a hideout after the Gads Hill Train Robbery in 1874. No hard documentation exists, but the canyon's isolated location and natural concealment make the story plausible enough to add texture to the walk.
The loop trail offers both creek access and elevated viewpoints from the surrounding bluffs. The total distance is manageable for most hikers, and the terrain has enough variety — creek crossings, stone steps, open bluffs, closed forest — to keep the attention engaged throughout.
