Theodore Roosevelt Island to Scott's Run Nature Preserve

This natural surface foot trail is the first trail to carry the name "Potomac Heritage Trail." It begins at the parking area for Theodore Roosevelt Island. The route is fairly rugged, especially the first four miles to Chain Bridge. After turning inland for awhile, the trail returns to the Potomac shoreline for a dramatic run up to Live Oak Drive at the Cabin John Bridge. Expect flooding at both ends in high water.
