The nature reserve offers various possibilities. The beach, the dunes and beautiful, long boardwalks. Occasionally information boards and a number of bird huts. On the beach many coastal poles and the bunkers of Escardines.

Many coastal poles were planted in the beach. They give the beach a beautiful stamp. They are there to stabilize the dunes and the coast and to protect them from erosion. The poles help to maintain the dune structure and prevent them from being washed away by the wind and the water. They play an important role in the preservation of the natural environment and the protection of the coastal areas.

On the beach to the North of Les Ecardines there are some bunkers which belong to the Infantry Stützpunkt Martha. This strongpoint with 2 bunkers laying on the beach was part of the coastal defence and observation. One of the bunkers on the beach is a Regelbau R120 observation bunker with a 21P7 metal cupola on top. It has three entrances and a armoured close defence opening for a MG. A flanking wall lies next to it in the sand. Next to the observation bunker is a Regelbau R630 type bunker. It housed a gun behind a big armoured plate. The armament of Strongpoint Martha consisted of MG’s in the R630 (MG stand for Machine Gewehr – machine guns), a 5cm M19 mortar, a 5cm gun, a 3,7cm Anti Tank gun, a MG-cupola, 2 Mortars and 5 MG’s. This heavily defended strongpoint housed the observation bunker of HKB Murane, as well as the headquarters of the 8th kompagnie. These bunkers, are part of a Luftwaffe Field Division instead of the Kriegsmarine. InfStp. Martha has eight bunkers in total. The other bunkers of this strongpoint can be found further up the dunes.
