The event spans nine days, beginning on a Saturday, and features around 600 balloons and 700 pilots, making it the largest balloon event in the world. Initially started in 1972 with just 13 balloons, the fiesta has grown significantly, now attracting up to 100,000 spectators on-site and many more watching from afar.
