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.
