The Wild Oak Trail (TWOT) is a 27 mile loop featuring big climbs and runnable trail. Elevations vary significantly, from a low of 1,600 feet at the trailhead at North River Gap to a high point of 4,351 feet on Little Bald Knob, and each loop boasts nearly 8000 feet of ascent. Portions of the existing trail were constructed by the Civilian Conservation Corps in the 1930s to provide access for forest fire control. These trails were combined as the Wild Oak Trail, which was designated a National Recreation Trail by the Secretary of Agriculture in 1979. In addition to the trailhead at North River Gap, there are two other road crossings on the loop: at FDR 96 and Camp Todd, each about 10 miles from North River Gap (in opposite directions).
Each year, Dennis Herr puts on TWOT in February or Hot TWOT in October, 100 milers comprised of for loops of TWOT. See the TWOT Web site for more information on these runs and The Wild Oak Trail in general.
