The Die grünen Geister geocache (GC469TG) is a short multi-cache that will take you about forty-five minutes. It was hidden in May 2013 by die Helden and werner54 in the Riedrode forest, in Hesse.
It belongs to the cluster of mechanical puzzle caches these owners have built up in the same spot, around the legend of the Nibelungs: Geist des Hagen, Schatz des Hagen, Alberich der Zwergenkönig, Alberichs Edelsteinturm. Several loops are suggested so you can combine a number of them: from one hour to a full day, depending on the time you have — a single car park, and a dozen caches among the most favorited in Germany. If you are travelling to Germany, this series is not to be missed under any circumstances.
