Koningsdag 2017! It used to be Queen's Day, then Queen Beatrix abdicated and her son Willem-Alexander became King of The Netherlands. It's still basically the same event, same vibe and same fun - just on a different day.
The streets will be filled with market stalls, parties, people and orange. If you've never been in Amsterdam for a King's Day or Queen's Day event, you should come see the orange madness yourself!
