The dune area north of Egmond Aan Zee, Duinlandschap Egmond Aan Zee , is part of the Noordhollands Duinreservaat. The area is also called the Blonde Dunes, as the colour of the sand is blonder because jet is sound, unlike the dunes north of Bergen aan Zee. (c) 6 July 2023 Aerophoto-Schiphol | aerial view 309935
