Réserve naturelle régionale du Grand-Voyeux - Congis-sur-Thérouanne

Bodies of water, ponds, and groves of poplar trees or sticky elm trees constitute today a haven of peace for numerous species of insects, reptiles, small mammals and especially rare birds. The “AVEN of Grand Voyeux” ensures the scientific monitoring of this area, which became a Natural Regional Reserve in November 2012.
The Association for Natural Areas Valuation of Grand Voyeux is responsible for the animation and the scientific monitoring of the site. Outings are organized regularly and communicated on the website.
