How can a trail be great and little? When it connects two of the Miami Valley's most popular regional trails, the Great Miami River Trail in the west, to the Little Miami Scenic Trail in the east. Today, the Great-Little Trail is a ribbon of smooth asphalt, branching off from the Great Miami River Trail just north of Crains Run Park. The trail heads east, traversing the Medlar Conservation Area. The 2.5-mile section through the preserve involves challenging climbs through mature woodlands to a hilltop vista, and relaxing rides across wetlands, fields and shrublands. The trail then continues for another 4 miles through suburban landscapes. The current terminus in Washington Township. Future work will continue the trail to make the connection to the Little Miami Scenic Trail.

Five Rivers MetroParks manages the Great-Little Trail (Route 34) from the Great Miami River and through the Medlar Conservation Area.
