The Heritage Trail Dog Park is open to all dogs and their owners who are 12 and older. The park is split into two sections – one for large dogs and one for small breeds. Park goers will find a shelter house with picnic tables, doggie splash pad, obstacle course equipment and plenty of room to play. The park is a joint project between the City of Hilliard and Columbus and Franklin County Metro parks. It is located at the Rails to Trails trailhead at Hayden Run Road.
