Rock Werchter is an annual music festival held in the village of Werchter, near Leuven, Belgium, since 1976 and is a large sized rock music festival.^[3][4] The 2003, 2005, 2006, 2007, 2012 and 2014 festivals received the Arthur award for best festival in the world at the International Live Music Conference (ILMC). It can host 88,000 guests daily, of which 67,500 combine all four days, to add up to a total maximum of 149,500 different attendees.^[5]

The festival started in 1974 as a one-day event with performances from Banzai and Kandahar, but over the years it has evolved to become one of Belgium's largest music festivals. Originally it was a double-festival, called "Torhout-Werchter", with two festival areas at different sites in Belgium: one in Werchter and one in Torhout. In 1999, the festival dropped the Torhout site and since then has taken place only in Werchter. Since 2003 Werchter has been a 4-day festival, as it was sold by owner Herman Schueremans to American organizers Live Nation. Schueremans however remains the main organizer of the event. The festival is organized every first weekend of the summer vacation in Belgium (last weekend of June or the first of July).

In recent years, there has been controversy about rising ticket prices. Because of this, Schueremans was heckled during an appearance on HUMO's Pop Poll, a Belgian alternative award show. At €200 for four days (€18 extra to include camping or €25 for xl-camping) in 2012, it was still considered by some a relatively inexpensive music festival.^[6]

The camping sites officially open at 8am on the first day of the festival, but because of guests arriving early and camping on the street, the organizers have traditionally been forced to open the camping sites early - sometimes more than 24 hours in advance. The campsites are located along the three main entrance roads into Werchter (from Haacht, Aarschot and Leuven), most of them within one kilometer of the festival site,^[7] but some are located as far as 3 kilometers away. In 2011, for the first time, XL camping tickets were available, allowing festival goers to arrive and camp from 4pm on the Wednesday before the festival.^[8]

Until the 1990s, the festival attracted mostly Flemish festival goers, but in recent years it has become more and more international with an especially large influx of Dutch, French, Walloon and British visitors, with notable Australian, South African and other contingents.^[9] Belgians alternatively go to the Pukkelpop and Dour festivals.
