Lots of fun, this vast water park has a cavalcade of pools, Jacuzzis and water slides, both indoor (year-round) and outdoor (summer only). In winter the ski centre here has five illuminated runs (the longest is 450m, with a 60m descent) and four lifts; ski hire's available. Take bus 355 from Kamppi bus station, or bus 582 from Espoo Central train station.
