Greene Swamp Preserve is currently open to the public.

To support community health and safety during the ongoing COVID-19 pandemic, please adhere to Massachusetts social distancing guidelines while visiting the preserve. This includes: maintaining 6 feet of distance from other groups, wearing a face covering or mask, maintaining group sizes of 10 or fewer, and thorough hand washing following the visit.

This preserve boasts a spring-fed cattail swamp, mixed woodlands and wildflowers, and rock outcrops.



Why You Should Visit 

Although named for the 10-acre swamp in the center of the site, the Greene Swamp Preserve includes additional interesting features such as a small stream, talus slopes and interesting rock outcrops on the southern slopes of Bull Hill, one of the peaks making up a distinct forested plateau-like upland east of the Connecticut River known as Mt. Toby. The Mt. Toby area is known locally for its unique geology and unusual plant and animal species. The numerous trails both in and around the Greene Swamp Preserve provide a wonderful escape for hikers, bird-watchers and cross-country skiers. The regional Robert Frost Trail goes through the Preserve.

Why TNC Selected This Site

The preserve is home to several rare plant and animal species as well as a regionally important wetland.

What TNC Has Done/Is Doing

Between 1993 and 2006, TNC protected seven tracts of land to create the Preserve. TNC has also assisted the U.S. Fish and Wildlife Service and the Commonwealth with additional purchases at the larger Mt. Toby site.
