About Rio de Janeiro
A cosmopolitan metropolis, known worldwide for its scenic beauty and its natural resources, Rio de Janeiro provides a harmonious and agreeable environment for its inhabitants and visitors. Those who have seen Carnival, a festival considered the biggest in the world, always come back for more. For first timers, the impact is unforgettable. The Parade of the Samba Schools in Rio is one of the greatest shows on earth. The parade is like an opera, in which scenery and fantasy float past the public, the story being told with the song, the symbols, the costumes and the floats, which year by year become more creative. The parade usually starts around 8pm, and goes on through the night, sometimes lasting until dawn, though the rising sun softens the effect and the show is more spectacular at night.
