Holden Arboretum
A vast Lake County landscape joins cultivated collections, native forests, ponds, and ravines with a 65-foot canopy walk and a 120-foot tower looking toward Lake Erie.

Artwork inspired by Joseph O’Sickey
Holden is less a conventional botanical display than a forest-scale laboratory. Collections of rhododendrons, lilacs, conifers, and maples meet natural areas used for research in forest health, climate, soil, and Great Lakes ecology. The Murch Canopy Walk carries visitors 500 feet through the trees at up to 65 feet high; the Kalberer Emergent Tower climbs 202 steps to a 120-foot panorama.
Do not let the towers consume the visit. Choose one garden collection and one natural trail so cultivated selection and forest process can be compared at ground level. The canopy structures are seasonal and weather dependent, and the tower is stair-only. A paved route provides an accessible approach to the canopy walk, while longer woodland trails vary sharply in grade, mud, roots, and distance.

How to experience an arboretum at three heights
- Begin at leaf level
- Compare labeled collections before entering less-managed forest.
- Cross the canopy slowly
- Pause at platforms to see branching, bark, and understory gaps from within the crown.
- Climb only if ready
- The tower requires 202 exposed steps and can close in poor weather.
- Choose one real hike
- Use the trail map; 3,500 acres cannot be sampled by wandering without a route.
Good to know
The canopy walk and tower are seasonal, weather dependent, and may close before the grounds. The tower is not accessible and requires 202 steps; visitors uncomfortable with heights can build a full visit around gardens, ponds, and woodland trails.
