Secret Garden Party 2009 will take place a secret location near Huntington, Cambridgeshire, which will be disclosed to ticket-holders when passes are dispatched. The festival will run from 23-26 July.
Tickets are on sale now priced at £137 (plus booking fee). Campervan passes are priced at £40, while teen (14-17 years) tickets will cost £110.
Organisers have also announced that the festival site will be split into two areas: Eden and Babylon. Each will be crafted either side of a lake, which will be centred by a Tower Of Babylon.
Bosses are also underway in preparing the festival’s infamous Action Camps including Science Camp with discussions, debates, art, music, films, experiments and demonstrations, as well as Conspiracy Camp and the all new Explorer Camp.
There will also be some very special boutique camping available, which will include private car parking spaces, where festival-goers will be greeted by Boutique Bell Boys, who will take revellers’ luggage to their site. It will also have its own security, private showers, posh loos, indoor sitting rooms, chill-out areas, reception service and onsite Boutique Butlers who will be on hand to fetch fans anything they desire.
Secret Garden Party won Best Small Festival at the UK Festival Awards 2008.
