The selection of sport and activities is very good and interesting: you can try climbing, beach volley, trambolines, Megazone (laser-gun battle)… Find out more from their website.
The sports complex is, however, pretty complex (staff is helpful and will guide you) – also getting here can be complex due to construction work! The area is former industrial area (still houses a power plant), that is now heavily developed. As such a fascinating area.
Salmisaaren liikuntakeskus is close to the Kaapelitehdas (cable factory) art & culture –centre, so you can combine sports with culture.
