After leaving the car parked at the recomended location, you can easily walk to the cache. Near the parking you will find the "Ermida Del Cristo De San Esteban" . This religious building is from either the end's of the XII or the beginnings of the XIII centuries.

The cache is a small "lock and lock" container and it has a travel bug for the FTF. To find it, just walk along the dirt track and when you get to the wall, it is on the other side, to the left, under a big stone. The cache is not in the wall, so please do not destroy it. The cache was hidden by The_Dukes, and helped by jflmatos and Tristão.
