The Samba Parade is something everybody should experience at least once in their life. The event is broadcast live to several countries. Watching on TV is comfortable but not close to as much fun as being there. Definitely mingle with the crowds and watch the Brazilians and Cariocas (the people of Rio). For the best and full blown experience, you can even march with a samba school.
