Just 20 minutes by bike from De Twee Bruggen you will find yourself in the middle of the fragile Korenburgerveen. The nature reserve is located northwest of Winterswijk and is an upland peat bog area that is home to special birds, mammals and reptiles.
This area was formed after the last ice age and once extended over a large part of the Achterhoek and the neighbouring area in Germany. Due to the development into agricultural land in the 20th century and the threat of drying up, little remained of the nature reserve. In 1918, Natuurmonumenten bought the area and the surrounding moors to improve water management and to enable the upland peat bog area to recover and function again.
