King's Night is the eve of King's Day, and in Amsterdam it is often wilder than the day itself. The city fills with outdoor stages, street DJs, and impromptu parties from late afternoon into the early hours. The Jordaan neighbourhood — especially Westerstraat — is the traditional heart of the celebrations, with bars spilling onto the street and music on every corner. Leidseplein and Rembrandtplein also host big organised events. Dress in orange, expect crowds, and plan your route in advance. The metro and trams run through the night.
