Open-air museum De Duinhuisjes consists of four historic dune houses between Oostvoorne and Rockanje. The houses are still decorated in the style that fits the period from which they originate, between 1850 and 1910.
A visit to this museum can be easily combined with a walk through the South Holland dunes.
