Hadwen Arboretum

Clark’s Very Own Forest

The Hadwen Arboretum, willed to Clark University in 1907 by Worcester resident and noted horticulturist Obadiah Hadwen, is located at the intersection of Lovell and May Streets on ancestral land of the Nipmuc Nation. Containing 26 acres of woodland green space in the heart of Worcester, the Arboretum lies at the midpoint of the East-West Trail, a 14-mile hike through many of Worcester’s parks and green spaces. By following this trail, you can visit Coes Reservoir, with waterfront access for swimming.

The Arboretum’s network of trails features many types of woody and herbaceous plants, including unusual species and many “heritage” trees over 100 years old. This unique green space invites nature study and provides applied research opportunities, such as research involving invasive species. The Arboretum is also home to a community garden administered by the Regional Environmental Council of Worcester.
