The Santpoortse Feestweek is an annual street party near my hometown of IJmuiden. Many people will spend the entire week partying and drinking during the summer. Some good events are the live street concerts, food stands (poffertjes,pannenkoeken,snoepkraam), funfair attractions and the horse races.
It was fun to see many of my highschool friends again after years of absence. I totally recommend this festival if you wonder how the local Dutch population celebrates their warm summers.
