The source of the Fichtelnaab is located on the southeastern slope of the Ochsenkopf ( sea level (NN)) northwest of Fichtelberg and west of the Fichtelsee (10.5 hectares and 752 m above NN). From there it flows southeast through the villages of Fichtelberg and Mehlmeisel in the district of Tirschenreuth. From there the Fichtelnaab passes through Brand, Ebnath, Neusorg and Erbendorf to Windischeschenbach, where it joins the Waldnaab.
