White Mountain National Forest

Park at the Dickey/Welsh Mountain parking area, located off Oriss Road in Thornton. To reach the parking area, follow NH Route 49 from Exit 28 on I-93 for 6 miles. Make a left on Upper Mad River Road, crossing the Mad River. In 0.7 miles Oriss Road diverges right ("Welch Mountain" sign). Follow this road for 0.6 miles and take a short right fork to the parking area. Follow the Dickey Mountain trail straight, past the "bike trail" arrow. The trail follows an old logging road uphill to a beaver pond where a single track begins from the right. The trail is marked by yellow blazes and climbs gradually to a knoll, then descends to an old logging yard, which is located at the end of Forest Service Road #23A in Mill Brook Valley. Follow the bicycle logos along logging roads to the Brown Ash Swamp Trail, or follow directions below for loop.

Loop Option: To loop back to the Welch and Dickey parking lot, follow the Forest Service Road 23A from the log yard. Bear left at the first intersection. Pass through the gate and take a right on to Mill Brook Road back to Route 175. Turn left on 175 and travel south for approximately 2.5 miles to Upper Mad River Road. Turn left, ride 3.5 miles to Orriss Road and the Dickey/Welsh Mountain Trail sign. Turn left to the parking lot.
