The High Blauen Road (Hochblauenstraße) was opened to private vehicles in 1928. About half the route is in the county of Freiburg-Hochschwarzwald. In its northwestern section it thus bears the designation K 4948, in the southeastern section it runs under the number K 6314, where the Wollbach highway agency is responsible. Winter clearance of the whole route is undertaken by the Müllheim highway agency by arrangement between the counties. The road runs to the top. Since 2011 during the summer months there has also been a bus route that links the summit on Sundays and holidays via Marzell and Kandern with Basle. In addition, variant A of the West Way, a long-distance path maintained by the Black Forest Club that runs for from Pforzheim to Basle, goes over Blauen.
