Puuhamaa is a amusement park opened in 1984 in the village of Tervakoski, in the municipality of Janakkala, Finland. Instead of electrical rides, it mainly offers things to do for children: slides and waterslides, bouncy castles, race tracks, etc. It also has a minigolf course and a video arcade. Its attendance peaks at roughly 5,000 children a day. The park has an entrance fee, but all its features are free.
