This Vill 027 is situated in the rocks with the name "Falaises des vaches noires". You can find the way up from the holyday parc EDF nearby les Genêts. The underground system Auberville was the underground barracks for the army unit that guarded the region. It was last visited by Henk Adriaanse in 2019. Two observation Vfs are more north.
Please be carefull.
