Salt Bay Heritage Trail

Length: 3 miles


  • moderate

Permitted Use:

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

Managing organizations: Coastal Rivers Conservation Trust

Trail Abstract:

Along with a large DRA conservation easement on private property, Salt Bay Preserve covers most of Glidden Point, which was bisected by Route 1 in the 1960’s. Beginning with boardwalks across a salt marsh, the three-mile Heritage Trail follows the shoreline of the Great Salt Bay before crossing under Route 1 through an old sheep tunnel. Soon thereafter, 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. Continuing along the trail, hikers pass through stands of large white oaks and meander along beaver ponds, ending back at the northbound ramp to Route 1. For a more thorough guide to the trail’s diverse natural communities, please pick up a “Salt Bay Preserve” brochure at Coastal Rivers.


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!
