Otter Brook Preserve

Harpswell Heritage Land Trust

Otter Brook Preserve runs alongside one of the largest freshwater streams in Harpswell. This freshwater marsh, stream, and pond system is a scarce resource in our coastal community.

All-season trails meander through the forest and provide 1.7 miles of pleasant walking, cross country skiing and snowshoeing. Visitors here enjoy quiet woods trails and glimpses of the brook and the wildlife that rely on it, including great blue herons, ducks and dragonflies. Otter Brook Preserve was protected from development by Harpswell Heritage Land Trust, numerous generous local donors and the Town of Harpswell to preserve its essential wildlife habitat and to protect the marine water quality for clams and other ocean life living in Ewing Narrows and Harpswell Cove.
