We went to the “Heidepark” (Theme Park) in Soltau in June 2010. We spend the nights at the hotel on the park ground, which is pretty cool since you can come and go as you like and you can change clothes if you get soaked riding a log flume. The motto of the hotel are pirates, so everything is in that design, which makes the rooms and everything look really cool.
The Heidepark itself is quite diverse if not that big, but still I enjoyed the roller coasters a lot.
