Assabet River National Wildlife Refuge encompasses 2,357 acres within the Sudbury-Assabet-Concord watershed. The refuge abuts the Sudbury River and Sudbury State Forest and is near Sudbury-Marlborough State Forest and Sudbury Valley Trustees Memorial Forest. The immense amount of protected land in this area gives way for diverse habitats, species and recreational uses. Assabet River has all six wildlife-dependent recreational uses of the Refuge System; wildlife observation, photography, hunting, interpretation, fishing and environmental education. In addition to these six recreational uses, this refuge has additional activities available for the public.
