Lahnis water entertainment park is an experience for everyone. Lahnis is all about doing together and offers multiple ways of entertainment – water activities, sunbathing and all kinds of sports on the beach.


Lahnis is conveniently located right between Helsinki and Turku, at the beach area of the nostalgic Lahnajärvi traveler rest spot. It’s not just a water park but a real entertainment center for the whole family, for the whole summer day – throughout the whole summer!







Summer 2017, come and try the new miniature golf! Opening partys face painting.




The youngest of the family have fun for instance in our water slides and bumping boats. Grown-ups spend the day in the sun relaxing on the beach and sun chairs. All of the activities are included in the price of the activity wristband.
