Open Ponds Trail is a 4.5-mile point-to-point hike across Hatteras Island, linking the British Cemetery by Buxton Woods Picnic Area with Frisco Campground. It is a segment of the Mountains-to-Sea Trail. The route moves among dunes, shrub thickets, maritime forest, and interdune ponds; this is an interior walk, not a beach hike. Keep it for a half day when you want a longer change of scene from the coast road. The listed distance is one way, not a loop, so walking back makes a 9-mile day. Arrange a pickup if you want the full crossing without retracing your steps. The ponds are part of the scenery along the crossing, not a single destination at the end.
