Auerberg, Mountain peak in southern Hesse, Germany.

Auerberg is a mountain peak in southern Hesse that rises as part of the Odenwald range overlooking the Rhine Valley plain. The summit features castle ruins that crown the hilltop and can be reached through hiking trails and roads.

The castle ruin on the Auerberg, known as Schloss Auerbach, is visible from the Upper Rhine Plain. The site lies on a 345.9 m summit that forms a south-southwest spur of the Melibokus. The two climbable towers give views over the plain, the Vorderer Odenwald and, in clear weather, as far as the Deutsche Weinstrasse, the Donnersberg and the Pfälzerwald. The south tower, closed for over 50 years, has a new staircase and is open again.

Locals call the hill Schlossberg, "castle hill", after the ruin on its summit; the older name Kleiner Malschen linked it to the Melibokus, its larger neighbour. The slopes below carry vineyards of the Auerbacher Rott, part of the Hessische Bergstraße wine region, and the Odenwald Club laid out the walking paths around the hill, among them the Blütenweg and the Weinlagenwanderweg.

The mountain can be reached by a steep road with parking available near the castle ruins at the top. Multiple hiking trails connect the summit to surrounding areas and offer different routes for visitors.

Two accessible towers remain from the castle and allow visitors to climb for views across the Rhine Valley below. These preserved structures offer a rare chance to experience the height and vantage point that once made this fortress so strategically important.
