If you want some challenging DIY and unique obstacles then this is for you. The park was just finished last summer(2012) and is free and very fun. Lots of pool coping and hard edge to hit and tight transitions. Great place and really friendly locals who all built the place.
To get there you nee to get yourself to the Rhein river on the side of KleinBasel. Follow the river towards Germany and when you hit Uferstrasse take it all the way down til you see the Grisard Bitumen Building. Look right and there it is. If you miss it, go and buy yourself some new glasses.
