Mühlsteinberg (483 m) is a forested summit in the eastern part of the Zittau Mountains, close to the German-Czech border. It's a quiet, atmospheric spot where sandstone rock formations and historical relics hide among the trees.

The summit is crowned by a sandstone rock, and about 100 metres to the northwest stands a slender rock spire known as the Mühlsteinnadel. In the late 1960s, the forest on the peak was cleared apart from a few mighty beech trees, opening up a wide view over the Zittau Basin. Today the mountain is forested again and covered in blueberry bushes, with the treetops now blocking the once-famous panorama. Still, the walk through this shaded, peaceful woodland has its own charm in every season, especially in autumn when the undergrowth turns golden and red.

• From Lückendorf — trail heading northeast, approx. 1-1.5 hours, easy difficulty
• From Eichgraben via the hairpin bend on the S 132 road (Gabler Straße) — approach from the saddle below Heideberg, easy to moderate

• On the saddle toward Straßberg lie the ruins of Karlsfried Castle and the Uhusteine rocks
• Along the path to Karlsfried, on the Klothildenhöhe rise, stands the historic Klothildenstein memorial stone from 1907
• At the top of the road's hairpin bend you'll find the Mühlsteintisch, a stone rest table from 1848 made from an actual millstone

Legend has it that the Klothildenstein got its name from a folk twist on Mathilde, the housekeeper of German postmaster Heinrich von Stephan, who frequently visited this area in the 19th century.
