Exploring Hoyt Arboretum’s 189 acres on our 12 miles of trail isn’t just a hike – it’s a worldwide tour of trees from around the globe.
The Arboretum is open year-round for self-guided hikes, aided by placards indicating tree species. Interpretive signs along your walk offer more information about the various collections. Pick up a free map in the Visitor Center to find suggested routes or download the map online.
