Lindenberg, Mountain ridge in Lucerne and Aargau, Switzerland

Lindenberg is a mountain ridge straddling the border between Lucerne and Aargau cantons at an elevation of 878 meters. The formation extends over several kilometers and serves as a natural dividing line between the two regions.

During the last ice age the Reuss glacier shaped the landscape leaving behind terminal and lateral moraines. The upper ridge remained ice-free and escaped the heaviest glacial carving.

The villages on the high terraces of the western slope, among them Bettwil, Schongau, Hämikon, Müswangen, Sulz, Lieli and Hohenrain, were farming villages; livestock raising and fruit growing still shape the open slopes. Near Beinwil, spring streams such as the Wissenbach and Sembach rise from the moraine ridges.

The ridge is crossed by marked trails and farm tracks; the highest point at 878 m lies in the Rüedikerwald in the canton of Lucerne and is flat and wooded, reachable on foot, by bike or by jeep. Horben Castle on the south-east side of the crest has four cross-country ski trails tracked in winter when snow allows, one of them lit in the evening. A small airfield lies on a terrace above Buttwil on the eastern slope.

The small airfield above Buttwil, on a terrace of the eastern slope, is used by sport and glider pilots; the Lindenberg ridge itself is crossed by marked trails and farm tracks, and its highest point at 878 m lies in the Rüedikerwald in the canton of Lucerne, close to Müswangen.
