The mountain tour starts from the lower Mühlgraben in Erb and initially leads along the Mühlbach via a forest road to the Mühlbachhaus, where the actual circular tour begins. At the crossroads there, follow trail no. 644 in the direction of "Kleiner Buchstein". The following section is characterised by forest roads, shortcuts through the forest and the sound of the Mühlbach stream, which you have to cross once further up. After the former Haslingeralm at approx. 1050 m above sea level, the trail becomes much steeper, you leave the forest behind and soon come to the Otterriegel crossroads (1485 m). From here follow the marked trail no. 645 southwards to the ridge between Kl. Buchstein in the west and the Tieflimauer in the east. The trail leads along the foot of the eastern walls of the Kl. Buchstein, becomes more sloping and therefore requires surefootedness. After a small loss of altitude, the trail finally leads through the Schneckenmäuer to the ridge, which you reach in a saddle. Continue on the high trail in a south-easterly direction. Head straight towards the Tieflimauer. However, the proximity of the summit is deceptive, as the entrance to the Teufelssteig (via ferrata B/C) is at the southeast foot of the Tieflimauer. This is why you have to walk downhill for about another kilometre before you reach it.
The via ferrata lives up to its name and it is therefore absolutely necessary to have a helmet and harness with you. After the exit, follow the ridge to the spacious summit, from where you can already see the next destination - the Ennstalerhütte. However, full concentration and sure-footedness are also required on the descent to the hut, because even on the normal route there are still a few secured sections for a reason. At the Teufelskreuz crossroads, you rejoin the high-level trail, which leads to the Ennstalerhütte with alternating ups and downs. To get back to the starting point, walk north at Landler Eck over the Landler Stieg'n and follow the marked trail no. 608 over the Bärensattel and several forest roads back to the Mühlbachhaus.
