Ah, yes. Carnaval. The party of all parties. These exuberant celebrations combine all of our favorite things - parades, live music, circuses, costumes and dancing, to name a few. The world's largest carnaval takes place every February in Rio de Janeiro, Brazil, where over two million revelers flood the festival streets each day.
