The High Rhön Road climbs steadily from there, crosses the B 279 at 476 meters above sea level and runs in curves, following the Schwarzbach stream, up to the Bauersberg and past the Rothsee at kilometre 4 by and past the Holzberghof Hunting Lodge at kilometre 6. From here the High Rhön Road enters the Rhön Biosphere Reserve at about 800 metres above sea level and reaches the highlands of the Rhön (Long Rhön). From here parking is only permitted at designated car parks and there is a reduced winter service (no salting). The High Rhön Road runs about 840 metres east past the 926-metrek-high Heidelstein. From the east it is joined by the road from Ginolfs.
