De Groote Peel is a National Park in the Peel, a region in the Southeast of the Netherlands on the border between the provinces of Limburg and North Brabant. It has a size of 13,4 km² and preserves a peat bog that has remained partly untouched by peat cutting, which used to be extensive in the area.It is one of the most bird-rich areas in Western Europe, with resident black-necked grebes and sometimes migrating common cranes in October/November. The terrain is varied with inaccessible peat swamps, lakes, heath land and sand ridges. The present swamp and some of the lakes were created by the cutting of peat.There is a 3 km-long route guided by red poles with a tower that provides visitors with a view of the wasteland. Those who do not want to follow the route but want to find their own way have to careful in these treacherous swamps.

It has become the way it is because of the harvesting of peat from the bog in the past. De Groote Peel offers a varied landscape of inaccessible peat swamp, lakes, open moorland areas, plains and sand ridges with purple moor. The current landscape of the Groote Peel was created by the excavation of peat. This excavation at some places created larger lakes in the marshy landscape. Around the mid 20th century ridges of trees were planted. The damp and quiet nature make the area attractive to birds. De Groote Peel is one of the richest bird areas in Western Europe. The area has a special vegetation of many rare species. It has been made accessible to visitors through the construction of raised trackways over the extensive swamp areas.
