I was strongly doubting that there would have been so many roller-coasters in this theme park but most where hidden by the hill. This park is a little paradise relatively close to the center of Helsinki with attractions of every kind, they have also a really old style roller-coaster with the driver!
There are also a couple of water attractions/roller-coasters really nice if you will be ready to get wet. The ticket price is not even so high.
