This is not a full amusement park, but it's an amazing play area for your kids for supper cheap (2.50 for kids and 1.50 for adults). The indoor area has a huge area for kids to play with Play Mobil and a cafe. They even had activities (varies throughout the day, coloring a crown and cutting it it for us). The outdoor area is huge and like a playground, but bigger. Our favorites were the pirate ship crawl area (below deck), the water play area, and the two story slide.

Warnings: There is an entry and exit through the gift shop, so you're likely to buy something. My kiddo picked out a 9.99 set, so all told, got out of there for under 20 Euro including admission, if you don't eat at the cafe. Also, we were visiting in July so the play area was also ridiculously hot and we only stayed out there a little while.

Note that parking is across the street. This is located next to the factory, so it's in an industrial area and you'll feel like you are going to wrong way until you see the castle.
