13-15th August. I am really keen to go but I will be doing some solo travel through Germany at that time, so if there are any groups heading there/other solo travellers in Germany at that time that are interested, let me know!
p.s. lineup for the uninitiated- http://www.haldern-pop.de/en/festival/line-up/
and Mumford and Sons are said to be joining the already-stellar list!
