How do I get the cache #1 Traditional Cache

This cache is part of a serie of a few geocaches where the method how to get the cache is quite different from other caches around here. 

This is the first cache of the serie. Others will follow very soon.

Have fun.

!!!!!! YOU DON'T HAVE TO FORCE THE "CACHECONTAINER" TO GET THE CACHE !!!!!!!

As it's already contained in the title, you have to find out a way to get the cache container.

ALL YOU HAVE TO BRING ALONG IS: A 1L BOTTLE OF WATER (not drinkwater, it would be a waste).

And don't forget, use your brain and do not force the cache container.

!!!Don't drive down to the woods, it's a forbidden road. Please park your car at the Church of Weiler-la-Tour!!!
