For years we have walked the barrancos of Cura. During the past years the thought came that it would be nice to have a few geocaches here. The oyster trail has gotten its name from oysters (or oyster shells), which have glued to rocks that are on the trail and lead you to the geocache and somewhere else but I won't say where. Come and experience.
The trail begins at a gate that is not a hindrance to hikers. In the beginning you may also see some art work that Professor Paul-Heinz Wohlers Allee has created for those passing by.
