We celebrated at a wonderful kids' indoor adventure park called Sensapolis. It is the perfect place for families with small children to teenagers!From rock climbing:
To a Castle
A Huge Tree House
A Space Station
There are also countless slides, science centers, craft area, and a small area just for toddlers and preschoolers.
The blur is me going 33km per hour!
We really had a great time. the price seems high, but with all that there's available to do, it's really worth it. Sensapolis will be expanding in December 2012 with a mini race track; we can not wait to return so we can try those out! For the full scoop, check out their site: http://www.sensapolis.de/de/inhalt
