Standing high above Saalfelden and showing an impressive rockwall to the south and southwest, Breithorn is one of the summits of the southern ridge crest of Steinernes Meer in the Berchtesgaden Alps that definitely deserves a visit. It is not difficult to climb on its northeastern normal route. After the Sandten parking area the road is closed for public traffic. Follow the road up to the supply cableway valley station of Riemannhaus. Follow then the trail number 401 steeply up into the valley between Breithorn and Sommerstein / Schöneck up to Ramseider Scharte and to Riemannhaus. Spectacular views to the Sommerstein tower that resembles a giant rock tooth in the saddle Ramseider Scharte between two majestic summits in the main ridge of Steinernes Meer: Breithorn and Schönegg. At Riemannhaus follow the signposts to Breithorn and Saalfeldener Höhenweg. The trail passes some nice karst features and climbes the northeast exposed, easy rock and scree slopes up to the summit without any extraordinary difficulties. Dachstein limestone and karst features characterise the scenery. Some 800 karst caves have been identified in the Steinernes Meer to date. Also typical is the distinctive plateau character of the Steinernes Meer above a height of 2,000 metres. Many fossilized shells of the old scallop Megalodon were found here in the Dachstein limestone. We finally reach Breithorn. From its summit you have really great views. The whole long ridge of Hohe Tauern on the south (with its highest summits Grossglockner, Grossvenediger, Ankogel and their glaciers etc.), the large karst plateau in the central part of Steinernes Meer and the jagged sharp massif of Watzmann in the background on the north, the huge ridge with the summit of Schönfeldspitze on the east and naturally Sommerstein and Riemannhaus. On our way back we have a good break at Riemannhaus.
