On the D940 take the exit les Quatres and follow the Landfront east towards Dondeneville. From there the defenceline goes towards Fontaine-la-Mallet. Along this route you see many small observationposts, Vfs for personnel and fine tobruks. We visited several strongpoints in this area: in the west Ha K 006, in the village Ha L 002 and in the east Ha L 005.
