The tunnel half-shell slide at the Airport Tower in the “Irrland” leisure park in Kevelaer / North Rhine-Westphalia is an absolute highlight and offers unique sliding fun. The adventure slide, which is operated with a slide mat, thrills its users with an incredible uphill and downhill ride, which is crowned by a bob run curve at the end. With its starting height of over 18.00 metres, it is one of the highest wave slides in Germany and Europe.
