Altweerterheide - red - 8,3 km

In the Middle Ages, the poor sandy soils in the area were sometimes used too intensively due to recurring deforestation, turf cutting, and grazing livestock. Even heathland no longer grew there at that time. Bare sand remained and began to drift under the influence of the wind. The drifting sand posed a threat to the surroundings and was curbed by planting, among other things, oak shelterbelts. Nowadays, the Tungelerwallen consists of a mix of coniferous woodland, gnarled oaks, and open sand. It is precisely the open sand that offers many special features, such as Iceland moss, bee wolf, and antlion, all species perfectly adapted to extreme drought and temperature fluctuations.
