Sønderkol is one of the highest points in the area - 102 metres above sea level. The effort of reaching the top pays off. You will be met by an exceptional view - From the top you can view the location of the annual rebild celebration, Gravlev Lake and you can observe the unique formations of the hills, the numerous walking paths, and grazing sheep that contribute in maintaining the unique heather landscape in the hills.
Various shrubs and bushes can be found in the hills. The beautiful hills are covered by heather, crowberry, lingonberries, blueberries, dwarf cornel, clubmoss, arnica, juniper, etc. The thickets consist of beech and scattered oak trees.
If the area is left untouched, the vegetation will spread to the entire area. In order to hinder the landscape turning into forest, the tree growth is removed by hand or machinery where it is neccessary. In addition, grazing sheep and cattle are utilized as nature management of dwarf shrubs, heather, crowberry and others.
The springs - such as Ravnkilde and Kovadsbækken - are created by groundwater that presses through the limestone in the soil. The springs contain unique insects, because the changes in temperature of the springs are minimal, around 7 degrees year-round. The flora in the spring area is also rare and vulnerable. Therefore, it is not allowed to walk in the springs. In the meadows surrounding the calcareous water, there are beautiful orchids, which should not be picked.
