Dimensions and shifting form
The dune is known for its exceptional scale: it reaches a height of around 100 m (328 ft) or more above sea level, making it the highest sand dune in Europe.tallest sand dune in Europe Its length is commonly given as close to 3 km (1.9 mi), and its width from sea to forest spans several hundred metres, creating a broad slope of loose sand.over 500 metres wide and 3 km long
The dune is not a fixed structure. Wind and waves move the sand so that its height and profile vary by several metres over the years, and the crestline slowly migrates inland.height oscillates between 100 and 120 metres Estimates suggest that tens of millions of cubic metres of sand form the body of the dune, accumulated over centuries by successive generations of dunes along this Aquitaine shoreline.55 million m3 of sand
A protected natural site between forest and ocean
Dune du Pilat is classified as a protected natural area, forming part of a Grand Site whose surface runs to several hundred hectares around the dune itself.506 hectares constitute the Grand Site Management of the site involves safeguarding both the dune and the adjoining coastal habitats, which include maritime pine forest, shoreline vegetation and the tidal environments of Arcachon Bay.
The dune’s setting creates a strong visual contrast: on one side the Atlantic waves break along a sandy beach, while inland a dense expanse of pines stretches across the Landes de Gascogne.border of the Landes de Gascogne forest From the crest, the view takes in the bay’s entrance, the Banc d’Arguin and the long strip of the Cap Ferret peninsula, with the dune itself forming a prominent landmark in this coastal landscape.contrast with the forest and ocean
