Asberg

The Asberg is a hill rising 441 metres above sea level on the northern edge of the Linz Heights. It belongs to the Rheinwesterwald Volcanic Ridge and was once the site of a basalt quarry. The hill’s stumpy dome stands about 80 metres above the surrounding plateau. Three small lakes, formed from flooded pits, lie scattered within 500 metres of the summit. The largest lake lies to the east and shows signs of silting along its edges.

The Asberg marks the highest point in three separate districts: Unkel, Rheinbreitbach and Erpel. Until the 1970s, workers extracted basalt from the hillside for construction. The flooded pits now provide habitats for local wildlife and form part of the landscape’s quiet charm. The hill’s volcanic origins are still visible in the exposed rock faces around the old quarry.

Visitors reach the summit along gentle paths that wind through open grassland and scattered woodland. The lakes offer calm spots for reflection and birdwatching. On clear days the views stretch across the volcanic ridge towards the Rhine valley. The contrast between the worked quarry scars and the peaceful lakes creates an unusual landscape worth exploring.
