Many thanks to Lobelt for restoring the cache. :-)
Apparently the cache has moved a bit from its original coordinates. Read the last logs for hints and coordinates. The cache is buried. It is easy to reach, but in spring and summer you might have trouble getting a decent GPS fix due to lots of tree cover overhead. However, you should be able to identifiy the location by narrowing in with the GPS and then looking for a small concrete structure on the ground. See the picture below for where to dig when you found the structure. The cache container is a standard 13x13cm fridge plastic box, it contains a pencil, a logbook and a little gift. A CD will possibly just fit in, but probably only without jewel cover. Please bury the container again carefully, but not too deep.
The surrounding landscape invites for a very entertaining, familiy-compatible walk in one of eastern germanies most scenic parks, designed by one of the very few non-conformist people in german history. Probably late spring is the perfect visiting time, although you might find the number of other visitors in the area then a little disturbing. Consulting your map you will easily identify the logical parking spot for your car. The area can also be reached by public transport rather convinient. If you want to stay overnight I can recommend sleeping in the pension rooms rented out by the Irish Pub O´Briens (http://www.obriens.de, N 51 45.555, E014 20.065).
