Geocache Description:

Regelbau L487 "Ringelnatter-Stellung" KRYLE Huge German bunker from World War II - still in good shape.

Our second cache - hidden in our favourite area in Denmark.

The bunker still is in a quite good condition. At the lower level the walls are still painted in yellow and white, divided by a small brown stripe. Not too much garbage inside and still visited regularly...

So be careful...


1. Coordinates mark the path to enter up the roof of the bunker - from here you need to find the entrance !

2. Downstairs...

3. Keep your eyes open...

4. Please hide the cache exactely as you found it. ...

User "treasurefinder70" placed a second box in the bunker without recognizing, that there is already our cache. Please only sign die logbook of the AURO93-Cache (it is a box with a blue cover)! If you find the wrong box (in a tunnel, red cord), please take it an throw it away !
