Located one mile from downtown Freeport at the head of tide on the Harraseeket River estuary, Mast Landing is actively used by area residents year-round.
The 140-acre sanctuary consists of open fields, salt marsh, an apple orchard, freshwater stream, and mature evergreen forest. Caretakers reside in the old farmhouse (a.k.a. Millmaster's House).
Mast Landing Sanctuary's open fields, apple orchards, alder lowland, and mature pine and hemlock forest provide a pleasant spot for walking, cross-country skiing and nature study.Mill Stream cascades over an historic dam and mill site before flowing into the tidal waters of the Harraseeket River.
The sanctuary attracts migrant shorebirds and songbirds and is a wonderful place to observe the courtship flight displays of nesting woodcock. Resident mammals typical of southern Maine woodlands include porcupine, mink, fisher, and deer.
