The Cologne Summer Festival continues to grow: the Cologne Summer Festival is coming to Haltern am See for the first time in 2026. The town in Münsterland will be transformed into a colourful sea of jolly costumes, good humour and Cologne music with a top-class line-up featuring Brings, Cat Ballou, Höhner, Bläck Fööss, Räuber, Klüngelköpp, Miljö, Druckluft and Björn Heuser. Another top act is already being planned and will be announced at a later date.
