Assabet River National Wildlife Refuge
U.S. Fishe and Wildlife Service
A Refuge to Call Your Own
The refuge encompasses 3.5 square miles located within the towns of Hudson, Maynard, Stow and Sudbury. While part of Fort Devens, this area was formerly known as the Sudbury Training Annex. The U.S. Army transferred 2,230 acres to the U.S. Fish and Wildlife Service in the fall of 2000. The first phase of the Assabet River National Wildlife Refuge is now officially open for wildlife dependent recreation. We ask that you help conserve this unique natural habitat by staying on designated trails.
The Refuge is open from one half hour before sunrise to one half hour after sunset. Wildlife dependent recreation opportunities, including hiking, photography, interpretation, and environmental education, are permitted on designated trails shown above. Please be aware of vehicles that may be operating on the refuge roads and trails. Future opportunities for fishing will be provided. Parking is currently available off Hudson Road. Additional parking is planned near White Pond Road. Walk-in access is permitted from both locations.
The initial phase of public use trails at Assabet River National Wildlife Refuge were opened to the public in March of 2005. Wildlife viewing opportunities increased on October 23, 2005 with a total of 10.5 miles of trails being added to the trail system. On January 11, 2006, approximately 2.77 miles of new trails opened for public access on the south side of Hudson Road. Printable Trail Map Please remember that you must stay on marked trails. We are not currently charging a fee for use of the refuge trails or parking area.
We will institute a fee program in the future.
The refuge is now open to hunting. Please check the link below (2005-2006 Hunting Regulations) for details on hunting opportunities, permit process, rules and regulations. A map showing the hunt areas can also be obtained at this same site.
Refuge lands are closed to horses, motorized vehicles, and bicycles. Dogs are not allowed. There are no picnic areas or campsites on the refuge. The large wetland complex and the contiguous forested areas found here today are important feeding and breeding areas for migratory birds. Help keep it that way by taking your trash with you upon departure.
