Near Newburg south of the Mill Creek Recreation Area, the Kaintuck Trail burrows into a nice refuge of the Mark Twain National Forest and is open to mountain biking. The 24 mile trail, shared by hikers, mountain bikers and equestrians, passes a 175 cave (natural tunnel) with limestone wall and slimy boulders. The route passes through green tunnels of foliage, untrampled trail and overgrown logging roads. The rolling terrain is gentle and presents several stream crossings.
To reach the trailhead from US44, use Exit 179. Head south on Highway T for 2 miles. Turn right on Highway P for 2.8 miles. Turn left on FS7550 for 2.3 miles.
The trail has 9 sections– Acorn Section follows an old logging road west of Kaintuck Hollow for about 4 miles. West from Acorn, Butterfly Section leads you down, through cedars, then over a dry streambed covered with large, mossy rocks. The Mushroom Section connects the Acorn and Pine Tree sections. Pine Tree Section is about 3 miles long. It runs parallel to a gravel road connecting Mill Creek Recreation Area with Hwy T. Squirrel Section connects to Oak Leaf Section, not far from the Natural Bridge and tunnel. Deer Track Section begins as a wide track. After passing a small lily pond, it loops southwest to Wilkins Spring and back to Acorn. Cardinal Section follows an old double-track on the ridge top for about a half-mile, where it branches to the east before descending into Kaintuck Hollow. Grouse Section runs south from Wilkins Spring intersecting with the Acorn Section.
Overall, Kaintuck Hollow Trail is the 3rd most popular mountain bike trail of all 27 mountain biking rides in Missouri.
