Salt Bay Preserve

Length: 3 miles


  • moderate

Permitted Use:

A great walk along the shore and woods of Great Salt Bay on a combination of boardwalks, bridges, and trails.

Managing organizations: Coastal Rivers Conservation Trust


Salt Bay Preserve skirts the northern and eastern shore of Glidden Point, which was bisected by Route 1 in the 1960’s. The 1.5 mile trail begins with boardwalks across a salt marsh and follows the shoreline of the Great Salt Bay before crossing under Route 1 through an old sheep tunnel. A spur to the shore allows access to one of Maine’s most important archaeological sites – the great and ancient Indian shell heaps of Glidden Point.


Trail use is recommended three hours on either side of low tide, as bridges and boardwalks become impassable at high tide. Low tide in Great Salt Bay is 2 hours later than it is in Newcastle. View a tide table here.

Directions to Trailhead:

The main trailhead for the Heritage Trail is located on the Mills Road (Rt. 215) in Newcastle, along the shore of the Great Salt Bay, just opposite Lincoln County Publishing north of Louis Doe’s and Route 1 by a few hundred yards. Please park in the Lincoln County Publishing lot close to Mills Road at the far end away from their office, and please do not block any of their vehicles!
