White Mountain National Forest

At Exit 29 on I-93 northbound, take a right turn onto US Rte. 3. Proceed south on Rte. 3 through the underpass and take the first right at the top of the hill—Adams Farm Road in the town of Thornton. Forest Service Road 378 starts at the first left turn onto a gravel road. Park along Adams Farm Road. Proceed up the road and around the Forest Service gate. Follow FSR 378 along the West Branch River to a fork where the improved road continues right and a rougher woods road bears left. Stay to the left, close to the river, crossing the Ellsworth Bog bridge, and continue uphill to Ellsworth Village Road. Either reverse direction or continue on Ellsworth Village Road to the intersection of Ellsworth Stinson Lake Road (paved). Turn left and follow the road to Rte. 3. Go left on Rte. 3, travel 2 miles to Adams Farm Road, and make a left to go back to the starting point.
