The Arboretum & Walk Maps

The Lower Olentangy Urban Arboretum

An arboretum is a “garden of trees” – to study, to build a sustainable environment, and to enjoy.

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 (see maps below).

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.

Printed maps can usually be found at the Arboretum kiosk, located by the Indianola Informal K-8 School parking lot, across from the School, at 251 East Weber Road, Columbus, OH 43202. Sometimes we run out of maps – let us know ( and we can print more, or you can print your own from the maps below.

The maps can be printed full size on legal or tabloid-sized paper (8.5″ x 14″ or 11″ x 17″) at Office Max, Staples, FedEx/Kinkos, etc. Save the map on a flash drive. You can also print the maps on legal or regular size paper on an inkjet or laser printer (click for full size, then click and drag to desktop or save the file if you want a copy).

In some cases, the markers may be damaged or missing. Let us know.

  2. You should have a route that goes through Walhalla Ravine (and up along California & Pacemont on other side). This area has quite a few native & non-native trees of large size that aren’t on your other routes, and would also offer a quieter route.

    • Hi Robert, At this point most of Walhalla Ravine and north are outside of the Urban Arboretum. Current boundaries are on the Google map above. There has been talk of expanding the Arboretum northward and you can contact the current chair of the Arboretum, Andrew Heckler, for more information (
