This is a well visited route, built for connecting the refuge A. Fronza alle Coronelle with the “Gartl” basin, the starting point of the climbs on the Vajolet Towers.

The easy metallic fixed rope trail starts just behind the refuge Fronza (2337 m) on a red “S” mark and ascends along stepping rocks, appearing as the edge of the large screed ledge being part of the entire eastern Davoi ridge. Follow the trail until the foot of the uneven rock face leading to the Santner Pass. Go on ascending on stepladders and stirrups, through rocky chimneys, valleys and rocky steps. Reach the narrow wind gap between the rocky needles of Schroffenegger and descend on a steep rock-bed with a metallic rope equipped ice canal (a part, which requests attention during the spring due the possible hidden metallic rope under the remained snow). Cross the canal and ascend left diagonally across over a sloping ledge and steep rocks. The exit is marked by a narrow short steep track and a small exposed face, to follow in northern direction until the southern edge of the boulders basin above the rocky labyrinth near to the refuge Santner Pass (2741 m).
In a few minutes from here, there are the legendary Vajolet Towers, which have been protagonists of the alpine history with the climbs of Tita Piaz, the “devil” of the Dolomites and with Georg Winkler, the climber, who firstly overtook the 4 th UIAA grade limit just on the rocky tower named after himself.
Descend to the refuge Vajolet and follow the way n. 541 along the majestic rock face of the Catinaccio until the junction with the way n. 550 passing the Coronelle Pass and leading back to the starting point.
