The Bristol International Balloon Fiesta is held annually during August in Bristol, England. Teams from the UK and other parts of the world bring their hot air balloons to the site and participate in mass ascents where as many as 100 balloons may launch at a time.
The event was first held in 1979 and is now one of the largest in Europe. It is common to have crowds of over 100,000 on each of the four days of the festival. It takes place in a large country estate Ashton Court. Mass launches are made twice a day, at 6am and 6pm, subject to weather conditions.
One popular attraction is the night glow, when balloons are inflated and glow to music after dark. These are held on the opening Thursday night at approx 9:30pm, followed by a spectacular fireworks display. There is another night glow at the same time followed by the fireworks on the Saturday night. Some people see these as the highlight of the fiesta.
The balloon makers Cameron Balloons are near to the fiesta site, in Bedminster, and make many of the special shaped balloons, which have included Rupert the Bear, The Scottish Piper, Bertie Bassett, and the Tesco Trolley. Many shapes have also attended the fiesta from abroad, over the years a UFO and a beaver have travelled from the USA, a Kiwi Bird from New Zealand, and an upside down balloon from the Netherlands.
In the past, the fiesta used to be held in the second week of September, but due to cancellations of flights and the muddy ground because of bad weather, it has been moved in the start of August. This has had a great effect as more flights manage to fly; cancellations are now normally due to high winds.
In 2003, the weight of crowds returning from the Balloon Fiesta and Ashton Court festival put such a great strain on the Clifton Suspension Bridgethat it was decided to close the bridge to all traffic, including pedestrians, during these events from 2004 onwards.
On the 10th of August 2013 they broke a balloon fiesta record after 74 balloons landed in one field near the former Cadbury's factory in Keynsham. The record was then broken a year later, when 90 balloons again landed in the former Cadbury's chocolate factory on 9 August.
