Assabet River National Wildlife Refuge walk

The Assabet River National Wildlife Refuge encompasses 3.5 square miles located within the towns of Hudson, Maynard, Stow and Sudbury.
Formerly part of Fort Devens, this area was known as the Sudbury Training Annex. The U.S. Army transferred 2,332 acres to the U.S. Fish and Wildlife Service in the fall of 2000.

The refuge has a large wetland complex, several smaller wetlands and vernal pools, and large forested areas which are important feeding and breeding areas for migratory birds and other wildlife. It also has 15 miles of trails, which are primarily flat.

Meet in the parking lot by the visitor center for a 90 minute walk.
