This trail is through a salt marsh and is .4 Km/.2 Mi. long. A short, but very interesting walk. It has special features for the blind. There is a rope that you can hold on to as you walk along the path. Every few yards there are signs on posts with information about the marsh (including sounds to listen for, things to feel and smells to sense) and where to go next, both written normally and in braille.
The trail is located on Cape Cod at the Salt Pond Visitor Center, National Seashore.
