Anyone interested in these type of "Alpine Coasters" (and you should be interested in them because they are amazing) should know there are some great ones within driving distance of Europa Park, most notably the Hassenhorn Coster:
While you are in the area of the Hassenhorn coaster, it's worth checking out Steinwasen park, a tiny hillside amusement park, with yet another alpine coaster, and many hillside toboggan type rides:
It even has an indoor powered toboggan slide (yes that exists) , complete with glacier theming and giant yeti:
The glacier building also contains a standard powered minetrain ride, and walk through which all interact with each other.
It also has an utterly bizzare children's darkride named "Historic Black Forest Train", which I wish I could find a video of.
Infact pretty much all the attractions at Steinwasen are bizzare and belong in this thread. Well worth a visit if in Europa Park area. Worth keeping in mind that all alpine slides and alpine coasters allow you to control your own car speed, so it's important to visit at quiet times, or you will be stuck going slowly all the way down behind small children! These things can be very dangerous if someone decides to stop their car, and the car behind comes crashing in to it at speed.
