The town of Duck offers one of the better waterside running options in the Outer Banks. This is a combination of a boardwalk/off road trail along the water that goes for 0.8 miles, and then a good section of Highway 12, with a decent shoulder and good water views, heading north toward Carolina Dunes. Start in town, and enjoy the boardwalk, and then head north on Highway 12, to Carolina Dunes. This would make for about a 5 mile run. Good water views most of the way. Duck is located at about the mid-way point of the Outer Banks, and its population swells in summer.
Add-On: Can continue north of Carolina Dunes, although water views are uneven. South of Duck, the road turns more inland. There are also weave along a few side-streets in Duck running east of Highway 12, toward the Atlantic.
