The 18-mile long Harmony-Preston Valley Trail connects the two communities it was named for. The northern two-thirds of this trail are built on abandoned railroad grade and are fairly flat. The southern segment leaves the constraints of the railroad bed and climbs to the rim of the valley with great views of the countryside. Stop and see a large sinkhole at the Karst Interpretive Site one-half of a mile from Harmony. A similar site is about a mile from Fountain on the Root River Trail.
Historic buildings and rural communities along both trails have points of interest to trail users. They also provide many services. Campgrounds, bed and breakfasts, restaurants, museums, outfitters, and unique stores are found in many of the trail towns.
Summer uses include hiking, biking, and inline skating. Trails are groomed for cross-country skiing in the winter.
At Isinours Junction the Harmony-Preston Valley Trail connects to the Root River Trail which runs from Fountain all the way through Lanesboro, Whalan, Peterson, and Rushford, and Houston for a total of 42 miles. The former rail bed follows the meandering Root River through spectacular limestone bluffs, picturesque farms, and small towns. It is generally flat and level, except for short stretches on its eastern segment.
