The Hadwen Arboretum, bequeathed to Clark University in 1907, contains 6.4 acres of unspoiled woodland green space in the heart of Worcester city. The Arboretum's network of trails and beautiful scenery offer a delightful sanctuary for hiking, picnicking, photography, quiet contemplation or even dog-walking. With over 40 types of plants, including unusual species and many 'heritage' trees over 100 years old, the Hadwen Arboretum invites nature study, while recent issues with invasive species offer ecological research opportunities. A Regional Environmental Council community garden is also in the Arboretum. The surrounding area, accessed by a walk through the Arboretum, includes Coes Reservoir. This beautiful space provides water-front access for swimming and enjoying the natural setting.
