The Lower Olentangy Urban Arboretum is located in historic Clintonville on the north side of Columbus, Ohio. It is bounded by the Olentangy River on the west, Glen Echo Ravine on the south, Walhalla Ravine on the north, and the CSX Railroad tracks on the east.
Over the last decade, hundreds of native trees and shrubs have been planted on tree lawns throughout the Arboretum area, and select trees are marked along two tree walks .
The ultimate goal is to grow a diverse, dense canopy of native species, connecting the ecological spaces along the Olentangy River and Glen Echo and Walhalla Ravines.
