This cache is located at an facillity for huntsmen near the rails. You can even take a look at Airplains starting and landing at the small airport nearby, if you are lucky...
The "Arschbach Pink Trail" is a short 2 hour biking tour without any athletic challenges, but with quite a lot of nice views and an easy cache-experience:-)
If you need a hint - try this: LINK
There are 7 traditional caches on the route from St.Peter/Au to Aschbach, which should be possible for everyone - BUT keep in mind: Don't enter the Railtrack!!!
