Spießhorn, Mountain peak in Black Forest, Germany.

Spießhorn is a mountain peak in the Black Forest standing at approximately 1350 meters, situated between the communities of St. Blasien and Bernau im Schwarzwald. A wooden viewing platform at the summit overlooks the surrounding ridges and valleys below.

The Spießhorn lies on the boundary between St. Blasien-Menzenschwand and Bernau im Schwarzwald, a line that has separated the two municipalities into the present day. The sources record no older territorial or border history for the summit beyond this municipal divide.

The name Spießhorn refers to the pointed shape of the peak, and the summit lies exactly on the municipal boundary between St. Blasien-Menzenschwand and Bernau im Schwarzwald. Walkers on the marked trails cross this line at the top, where the small observation pavilion stands among the trees.

Marked trails lead from Berggasthaus Krunkelbach-Hütte to the summit, covering a distance of one to two kilometers. Sturdy footwear and adequate water are important to bring, particularly on warm days.

The summit pavilion stands on the boundary line itself: the municipal border between St. Blasien-Menzenschwand and Bernau im Schwarzwald runs across the top. Southwest of the main summit lies a subpeak, the Kleines Spießhorn, which the sources name but describe no further.
