6. Glass Beach (Fort Bragg, California)
In 1900s it was permitted to dump garbage into the waters of the area. Because of this, the city of Fort Bragg is now famous for its unusual pebbles that were once formed from glass plates and bottles. It is not dangerous to walk on them since the edges are smoothed by the water. It looks as if marbles and candies were scattered by some naughty kid all over the place – the beach is colorful and does not look anything like the beaches you have seen before.
