Site description The least spoiled dune area in the Netherlands, located between Oostvoorne (close to 021) and Haringvliet (024).

This site, together with sites 020 and 023, formed part of a single, larger site (former site NL046) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
Key Biodiversity A small dune-slack holds breeding Platalea leucorodia and Phalacrocorax carbo.
