A special geological highlight is the Windsborn crater lake which is part of the Mosenberg volcano group. It was wrongly referred to as Maar in the past but today it is clear that its origin was different.
In its monumental form made of basalt lava stone, the castle gate in Nickenich is an ornament of the place.It was once the entrance to the farm buildings in the castle district.
Kornelimünster with its churches worth seeing and old town houses, the former monastery and today's museum offers an excellent ambience for strolling. Important art treasures, the "Historical Fair" in June, the Korneli Octave in September and the Christmas market are reasons to visit the pilgrimage site. The pubs in the romantic alleyways attract walkers and stopovers. Kornelimünster is the starting point of the Eifelsteig long-distance hiking trail, which runs 313 km in 15 stages through the Eifel to Trier.
