While America is home to fantastic beaches, it is surprisingly far down on the list of longest coastlines. Still, the U.S. can boast 12,380 miles of coastline, which includes those of Hawaii and America's territories. Of the 50 states that make up this country, a whopping 23 of them have at least a bit of coastline, with some states bordering the Atlantic Ocean and others bordering the Pacific. Alaska touches the Arctic Ocean, and the Gulf of Mexico creates a coastline in the south.
