    Cape Hatteras Lighthouse, North Carolina

    Just off Cape Hatteras lies one of the Atlantic coast's most dangerous stretches of sea: the area where the Gulf Stream collides with the Virginia Drift. Hundreds, if not thousands, of ships have met their demise here, earning the region the nickname, "Graveyard of the Atlantic."

    Cape Hatteras Lighthouse has been warning ships in the area since it was first lit in 1803. The tower's height was increased 1853 and again in 1871. At 210 feet, it's now the tallest lighthouse in America.

    In 2000, increasing beach erosion led to the lighthouse being moved 875 yards inland. The site now features a museum and visitor's center. Climbing tours of the lighthouse's 248 iron spiral stairs are held daily in spring, summer and fall.
