A stage with two faces: the first part runs from east to west over an elongated series of land dunes, with the Oudsberg as the highest dune of the Kempen. The second part leads you to the site of the former Waterschei coal mine (Thorpark). From the top of the slagheap you have an almost complete view of the National Park. For those who want to, this "Gateway to the National Park" is a worthy end of the trail. There's a regular bus service from here to the train station of Genk.
