The Little Miami Scenic Trail (LMST) is one of the longest paved trails in the United States, spanning 78.1 miles (125.7 km) through five southwestern Ohio counties. This multi-use rail trail experiences recreational use by hikers, runners, and bicyclists--and in Greene County, also by horseback riders. The LMST is signposted as State Bike Route 1 south of Xenia and State Bike Route 3 throughout its length. The largely wooded corridor was created along the former Little Miami Railroad. The original railway bed remains visible beside the trail in various locations.

Trailrun around the City of Vienna.
