Since 21 May 1887 the Höllental Railway, with its station in Hinterzarten has linked Breitnau to the national railway network. The former railway stations of Hirschsprung, Posthalde and Höllsteig (near the Ravenna Gorge), which all lie within the municipality of Breitnau, are no longer served. In addition, Breitnau is served by bus lines 7216 (Freiburg – St.Peter – St. Märgen – Breitnau – Hinterzarten) and 7261 (Neustadt – St. Märgen) run by the Südbadenbus company.
