I'll give you that Frenchie. 9.5% of the land area of France is national park area - this could be the highest in Europe, depending on definition of Europe. Iceland has 12.1% - but classifying it as Europe is problematic. Also Denmark has a much higher percentage if you include the North East Greenland National Park, which is the biggest in the World. Over to you.Judging by the number of signs I see about regional parks, I will have a guess at France.
