Visit Us
Meadows Sudbury Unit includes tranquil trails around wetlands including the Sudbury River and up through woodlands and fields. The Eastern MA Complex headquarters located here is adjacent to the river at the base of Weir Hill. This hill – a 12,000-year-old glacial deposit – was used by Indigenous peoples who trapped fish in the river by creating fish weirs; hence the name of “Weir Hill”. Visitors can explore via canoe or kayak in the Sudbury River to get a remarkable wildlife watching experience on this unit of the refuge.
Great Meadows Concord Unit is unique piece of property, with several trails available for wildlife observation. This land was donated by a local hunter, Samuel Hoar in 1944. Mr. Hoar was an avid outdoorsman, he tried to conserve the wetlands by creating dams and dikes to keep the wetlands flooded for waterfowl. He donated his land to U.S. Fish and Wildlife to help conserve the wetlands for the future. Visitors can travel through open grasslands, mature forest, around wet marshes, and alongside the Concord River. The observational tower and pier allow for great wildlife watching, especially birding. Noted ornithologists consider the Concord Unit to be one of the best inland birding areas in the state.
Please note: there is an entrance fee the Concord unit.

Great Meadows Concord Unit: This unit has a large observational tower easily accessible from the parking lot and an observational pier off Dike Trail in the middle overlooking the lower pool.
