Landscape attribute:

This was formerly  an area of impenetrable frontier forest, but is today a cultured landscape  formed for centuries by man. You can see basalt and phonolite mounds and bizarre  sand rock formations throughout the area. There are forests gradually changing into foothill meadows rich in hedgerows and solitary trees. Traditional Lusatian architecture has been conserved in many places. The forests are dominated by the spruce, although some indigenous forest woody species (beech, fir, maple and elm) have been conserved in some barely accessible and remote places. There is oakwood around Klíče peak (748 m), which is unusual at this altitude in Bohemia. Centuries-old yews grow in the  town of Krompach. The agricultural landscape is formed mainly of meadows and crops interlaced with growth, hedgerows and riparian stands along streams, where the remainder of many precious plant and animal species have been conserved.

The constitution of the bedrock is remarkable. Upper Cretaceous sediments have been broken through by Tertiary neo-volcanic rocks in many places. Along the Lužický fault some basal Cenomanian conglomerates and Jurassic limestone have been occasionally pulled up to the surface. A small part of the northern edge behind the Lužický fault consists of granite and unique crystalline complex.

The Lužické Hory Mountains represent the watershed of the Northern and Baltic seas  and a  significant weather  break. The weather often significantly differs on the northern and southern slopes.
