I am 21 looking for the must see things in Germany in June/July 2014, will probably be spending around 20 days in Germany on a budget of about €150 per day give or take. I am travelling with my brother and friend who are the same age as me. I am open to travel Germany in that time. I have no dates set so throw as many options at me as possible.
Basically looking for festivals and events that have a party scene, or once in a lifetime experience, or something that you just cant miss out on.
Any help is appreciated :)
