Large contiguous natural areas are very scarce in the Netherlands. Only some scattered parts remain from the vast peat-moors, called "De Peel",  that once covered the border area of the dutch provinces Noord-Brabant and Limburg. The largest parts are National Park "De Groote Peel",  Deurnsche Peel and Mariapeel.  They are managed by the dutch Forestry Service (Staatsboshebeer) as one united area. Next to the larger parts there are some, mostly small, areas of heather, forests and moors.
The NP is partly closed for visitors in spring and autumn. In spring because of the breeding season, in autumn because of bird migration (a.o. cranes). You can find more information on the NP's  website (in dutch).
The location of the larger areas is outlined below.
