The historic quarry "Ahl" lies south of the municipality of St. Johann in the Vordereifel. The imposing rock face rises steeply north of the Nettetal and is visible from afar due to its yellowish colour.
With 747 m it is the highest elevation of the Eifel ! The " Hohe Acht " is a tertiary volcano and last but not least because of the 16,30 m high " Kaiser-Wilhelm-Turmes " on its top since 1909 visible from afar.
The heath garden on the Wabelsberg near Langscheid is both a nature trail and a botanical garden and provides information about the characteristic plant species of the heath.
