One of the most famous beaches in the world is Copacabana. This 2.2 mile stretch of sand facing the ocean is visually bookended by Sugarloaf Mountain in the north and Fort Copacabana in the south. Activities are simple: swimming, sunning and socializing. More active folks use the volleyball nets or football courts, run or jog, or strut their stuff on exercise equipment. Copacabana is also the site of New Year’s Eve fireworks. Two million people show up to watch the third largest display in the world.
