Červená hora, Mountain summit in Hrubý Jeseník range, Czech Republic.

Roter Berg, known in Czech as Červená hora, is a 1,333-metre summit in the Keprník highlands of the Hrubý Jeseník range, on the historical border of Silesia and Moravia. Its slopes are mostly mixed forest with spruce stands, clearings and glades; the summit itself has a small bare area and rock outcrops with rich flora. The eastern slopes lie within the Sněžná kotlina nature reserve.

The mountain historically marked the boundary between Silesia and Moravia. A historical triangulation station was established at the peak to record its precise elevation for mapping purposes.

A legend tells of a monk who survived a night on the mountain by drawing a protective circle against wild animals, giving it the name Red Mountain.

No marked trail reaches the main summit; the summit yellow marker branches off the red ridge route from Červenohorské sedlo and rejoins it at Sedlo pod Vřesovou studánkou. The summit lies 3 km north-northeast of the pass, or about 5 km from Keprník on the opposite side. A green-marked path via the Točník forepeak offers another approach.

About 600 metres north of the main summit lies Kamenné okno, a rock window or natural arch that visitors often overlook. The summit itself has no marked trail, so the arch is reached only by unmarked paths through the forest.
