The Mountains-to-Sea State Trail (MST) is a long-distance trail for hiking and backpacking, that traverses North Carolina from the Great Smoky Mountains to the Outer Banks. The trail's western endpoint is at Clingman's Dome, where it connects to the Appalachian Trail in the Great Smoky Mountains National Park. Its eastern endpoint is in Jockey's Ridge State Park on the tallest sand dune on the east coast. The trail is envisioned as a scenic backbone of an interconnected trail system spanning the state. As such, the trail's route attempts to connect as many trail systems and natural scenic areas as practicable. A little over half of the trail is complete in multiple segments across the state.
