Trail Overview
Twin Mountain (FS 418) is a semi-maintained gravel Forest Service road within the Willow Springs Unit of Mark Twain National Forest. It logistically leaves the Missouri South Route 181/Blue Buck Knob scenic byway, heading south into the forest, first crossing a small valley with a water runoff washed section, to then track back uphill, with great views of the Blue Buck Tower to the west, before shortly passing along the east side of Dyestone Mountain, with a valley to its northeast featuring a small natural bridge to walk down to and check out, before riding slightly downhill to a gate where the MVUM-sanctioned road ends and turns into an admin-only motorized road, though this gated section can be hiked and explored on foot, eventually passing on the eastern side of Twin Mountain, which as scenic views in multiple directions at its location. There is a 3-point turn around just north of the gate's location to turn around or park to continue south on foot.
Difficulty
Twin Mountain is given a base rating of 2/10 for having mild water washes and erosion, in the water runoff crossing, and on the mild grades along the track, as well as having all the common gravel road complications, including potholes, washboarding, and mounding of the gravel, as well as spots that fade to dirt and surface mud. Difficulty could increase during heavy use, wet conditions, or severe lack of maintenance.
History
On the weekend of March 21st, 2026, OnX Offroad partnered with local organizations, Rallye In The Ozarks, Heartland Trail Trash, and Critter's Clean Up and Cruise, to host an OnX Offroad Trail Revival Project, to remove 3 large illegal tire dumps, and conduct an additional litter pick-up. The results were impressive, yielding 348 tires and 3000lbs of trash (including an ice chest, 4 couches, and a variety of small litter) being removed from the Mark Twain National Forest in that singular day. Twin Mountain yielded small amounts of litter being picked up along its edges as well as at its main dispersed campsite. Documented by Christopher Menz in 3/2026
