The Lunken Airport Bike Path is a 5-mile loop trail that circles Lunken's airport. Much of the trail sits atop the levee that protects the airport from flooding of the Little Miami River. The paved path is wide and affords many nice views of the airport for those plane-spotters. You also get nice views of the river in places.
The Lunken Airport Bike Path links to the Armleder Park Trail
