The rocky landscape of the Noumerleeën delimits the distribution area of the Luxembourg sandstone in the Natur- & Geopark Mëllerdall. To the northwest, the gently undulating landscapes of the marls of the Keuper period follow. The Noumerleeën can be seen as a miniature image of the entire sandstone region. Almost all geologically interesting aspects can be discovered here in a small area: on the rocks, the depositional layers and various forms of weathering are clearly visible. The honeycomb weathering is reminiscent of honeycombs. The narrow passages (LU: Schlëff) and half-caves are also found here. Rock overhangs, which were used as campsites by our Stone Age ancestors, for example, the Alebuerg refuge on a rock spur and charcoal burning sites, are traces of past human uses, some of which can be observed in the terrain.
The hiking trail Autopedestre Nommern 1 passes the Noumerleeën.
