Montsweag Preserve is a 50-acre preserve that sits directly across from the Chewonki waterfront and includes a mix of rocky and salt marsh shoreline in addition to a beautiful stretch of coastal forest. The property was transferred to Chewonki in 1994 and ensures that our waterfront will be protected from marine-related development forever.

The Eaton Farm & The Back River Trail are adjacent to Chewonki Neck to the east. Maine Yankee Atomic Power Company finalized its donation of 200-acre Eaton Farm to Chewonki in 2005 as part of a Federal Energy Regulatory Commission settlement agreement. Chewonki agreed to create a nature preserve, maintain public access, foster stewardship of the estuarine environment, and provide a forum for dialogue on environmental policy issues. The Back River Trail got underway in 2005 – with 4.5 miles of trail opened to the public in 2006. This leg is the first in a long-range plan for a trail from Chewonki Neck to the Town of Wiscasset.

The Cushman Preserve anchors the northern end of the Back River Trail, linking the trail to Birch Point and the Wiscasset waterfront to the north and the former Maine Yankee lands to the south. This 147-acre property came to Chewonki in several pieces. The donors have requested that we maintain the tree farm first established on the land in the mid-1930s, as well as keeping the pasture open for the enjoyment of the public.
