Van Tour
If the idea of buying a van and driving around Europe appeals to you and you want to do it with hundereds of new yobbo friends, then van tour will probably be up your alley.

I'd never heard of it, but most Aussies and Kiwis have. Basically, it's an informal way for people driving around Europe, usually in an old van, to meet up for major events and everything of note in between. Major stops include Pamplona for the Running of the Bulls and Munich for Octoberfest.

It's not an organised tour though, as the name would suggest. Vans can join in or leave as they see fit, and to be a part of it all you really need to do is buy a van and hook up with other vans along the way in campsites and at festivals across Europe. The 'tour' usually starts in Pamplona at the Running of the Bulls and weaves it's way through Europe before ending in Munich at Oktoberfest for a monumental, feral pissup at the '100 Club'. I have spent lots of time hanging around with Aussies and Kiwis in London and can guarantee that going on van tour will be an amazing experience and you will probably never party as hard again in your life.
