You can always find a plethora of dancing people on the terrace of Club der Visionäre.
With countless colourful lights this open air location is especially inviting on summer weekends for waterside chilling.
There are also a lot of tourists partying there, so be prepared for long waiting lines and often there is not much space on the dancefloor to actually dance. The club loses some points over this since their choice of music is really made to party.
