Rötelstein, Mountain summit in Filzmoos, Austria.

Rötelstein is a cone-shaped mountain in the Dachstein Massif, in the municipality of Filzmoos, Salzburg, reaching 2247 metres and falling steeply on all sides. Its summit carries a summit cross with a summit book. Marked routes lead up from the east via the Sulzenhals and from the west via the Ahorneggalm.

The sources document no medieval grazing routes on Rötelstein. The mountain stands in the municipality of Filzmoos, St. Johann im Pongau district, in the western Dachstein Massif, and is climbed today by two marked routes: from the east over the Sulzenhals and from the west over the Ahorneggalm. A summit cross with a summit book stands on top.

The summit carries a Gipfelkreuz with a summit book, where walkers on the marked routes from Sulzenhals in the east or the Ahorneggalm in the west sign their names. The mountain is also called Rettenstein, a second name used alongside Rötelstein.

The mountain is reachable via marked trails starting from Rettensteinhütte Car Park, with the full circuit measuring about 9.8 kilometers. The terrain is steep and rocky, so sturdy footwear and a moderate fitness level are essential for the roughly 5-hour journey.

The summit holds a summit cross with a summit register (Gipfelbuch), where climbers record their ascent. The mountain is also known as Rettenstein. Two marked routes lead up: from the east over the Sulzenhals and from the west over the Ahorneggalm.
