Olentangy River Parklands give Worthington its easiest dose of river scenery, with paths, woods, and open spaces along the Olentangy. It is a local park system, but a useful one for travelers who want a walk between historic-town stops.
The parklands work best in combination with Old Worthington rather than as a destination on their own. Bring walking shoes, expect simple facilities, and use the trails to see the quieter residential edge of the city.
