Beach! The one word comprises everything there is to say about Copacabana, but then it's a word that contains within it an endless variety of human behavior. Four kilometers (2 1/2 miles) long and bright white, Copacabana beach is the stage upon which people swim, surf, jog, preen, make sand castles, sunbathe, and play volleyball. The broad and beautifully landscaped Avenida Atlântica runs along the beach's entire length. Running parallel two streets inland, Nossa Senhora de Copacabana is the main shopping and commercial street. These two avenues and their many cross streets contain numerous hotels, restaurants, and bars.
