The Albuquerque International Balloon Fiesta is the world´s premier balloon event. It is a huge 10 day event held in Albuquerque, New Mexico, USA at the beginning of October each year. It attracts an amazing 500+ balloons, thousands of balloon enthusiasts and professionals, and hundreds of thousands of spectators. It was first held over 40 years ago and has grown massively since then. Particular highlights are mass ascensions, when the majority of the balloons take to the sky, and morning or evening "glows" when many balloons light their burners at the same time. Activities start at 6am or so in the dark when the first balloons fire up and take off to take advantage of the normally still morning air.
