What U.S. state has the longest coastline?


With 6,640 miles of coastline, Alaska tops the list of U.S. states exposed to the ocean.

The state’s Pacific coast alone amounts to 5,580 miles, while the Arctic coast comes in at 1,060 miles long. Unlike the coastlines of many other states, however, the coast of “The Last Frontier” is rocky, icy and often at temperatures below freezing. In fact, most of this coastline is uninhabitable! Alaska also boasts the most shoreline mileage, at 33,904 miles. Source: NOAA Office for Coastal Management, SmashingLists
