Kneippbyn is Gotland's main family amusement stop, a short drive south of Visby. Its best-known feature is Villa Villekulla, the colourful Pippi Longstocking house used in the Swedish films, which gives the park a cultural hook beyond ordinary rides and water slides.
The site is most relevant for families spending more than a day in Visby or looking for a child-focused break from medieval walls and church ruins. It is seasonal, so check opening dates carefully before planning a trip around it.
