Still on the charming SS52bis, we ascend to the Monte Croce Carnico / Plöcken Pass (km 11), and then down to Mauthen (km 22). Entering the beautiful Gailtal valley, we meet Sankt Jakob im Lesachtal (km 31), Sankt Lorenzen im Lesachtal (km 45), and then enter Maria Luggau (km 49). After Untertilliach, we pass through Obertilliach, and up a little further to the Kartischer Sattel (km 65). With a beautiful descent, we pass Kartisch, and return into the Drau valley at Tassenbach (km 74). In short, to the state border at Prato alla Drava (km 81), then San Candido / Innichen (km 89), Dobbiaco / Toblach (km 94), and Villabassa / Niederdorf (km 100).
This is the most demanding stage of the 1200 km. The climb to the Passo di Monte Croce Carnico / Plöckenpass is very even and on a state road with little traffic. Pay attention to the descent, which is steep in places, on the cold Austrian side. There are several tunnels, the first in particular is long and steep. The road through the Gailtal Valley, with several ups and downs and a few hairpin bends, is the main road, but has light traffic.
