This nearly-level trail follows Grace Coolidge Creek, crossing it many times as it meanders through the valley. You’ll happen upon six low head dams, built in the 1930s by the Civilian Conservation Corps. The ponds and creekside offer excellent trout fishing and provide habitat for a variety of plants and wildlife.
