Ammonoosuc River includes a variety of landscapes while passing through several small historic mill towns, plus over the 345-foot covered bridge in Bath, NH, which dates from 1832 and spans an adjacent waterfall in the river, and the Lisbon Depot. Between Littleton and Lisbon riding the former railbed of the Boston and Maine Railroad, you can traverse a variety of terrains including forest, wetlands, fields, and farmland. These 4-wheeler trails are part of the larger 83-mile Cross New Hampshire Adventure Trail system between Woodsville, NH, and Bethel, Maine.
