This is a big giant spectacle all over the downtown area. They are parades and people in costume…read more I only went once see the parade, since it was complete Mayhem. It doesn't look it but this was the street going towards the parade. There's no way to feel lonely during karneval. You have to be holed up at home to avoid people during this time in the city. Best to get into a costume and meld into the crowd.
