Water and Ham Festival
Lanjaron, Spain
23-24 June

This is arguably the best water fight that you can find in the whole world. Actually it takes place in the Alpujarras Mountains, Granada in the South of Spain. As from midnight on the 23rd of June, each person will attack each other with all the water that they can get.
It does not matter whether you know the person or not as people will be soaking each other in the streets while others will use their hosepipes to soak those below their balconies. And when the whistle blows at the end of the fight, the real party will start with the cerveza flowing in full flow. A really great festival.
