The Langenberg's neighbouring peaks include the Hoppernkopf () to the north, the Mittelsberg () to the east, the Hegekopf () to the east-southeast, the Hopperkopf () to the southeast, the Clemensberg () to the south-southwest and Auf dem Sternrodt () to the west.
There few trees on the Langenberg's rounded summit itself and it widens out into a mountain heathland to the east; the rest of the mountain is, however, thickly forested.
