Copacabana is located in the South Zone of the city of Rio de Janeiro, Brazil. It is known for its 4 km balneario beach, which is one of the most famous in the world. Copacabana begins at Princesa Isabel Avenue and ends at Posto Seis (lifeguard watchtower Six). Beyond Copacabana, there are two small beaches: one, inside Fort Copacabana and other, right after it: Diabo ("Devil") Beach. Arpoador beach, where surfers used to go after its perfect waves, comes in the sequence, followed by the famous borough of Ipanema. The area will be one of the four "Olympic Zones" during the 2016 Summer Olympics. (Wikipedia)
