The Kleiner Arber, sometimes also the Little Arber, in the Bavarian Forest is a mountain, 1,383.6 m above sea level (NHN), and the highest peak in the Bavarian province of Upper Palatinate. The border with Lower Bavaria runs over its summit and that of the Großer or Great Arber (1,455.5 m above NHN) to the east. An elongated rock outcrop west of the summit cross is the actual highest point in the Upper Palatinate (1,439.6 m). On the rocky summit is an imposing wooden cross and summit register. The view extends over the Lamer Winkel into the Zellertal valley.
