From the Frommeralm car park, a chairlift will take you to the Kölner Hütte mountain refuge hut. The via ferrata begins behind the Kölnerhütte mountain hut (Rosengarten) hut, at 2,339 m. The route leading to the via ferrata takes you over easy climbing stretches below the Baumannkamm. The via ferrata begins with a lengthy ascent, secured by steel cable, until you come to a ladder, which is followed by a short, easy descent. In spring, this stretch is normally iced over. The following section calls for absolute surefootedness, as it leads over an unsecured rocky trail. The Santner via ferrata ends at the Refuge Santnerpass mountain hut at 2,734 m, where you can enjoy the fabulous view of St. Zyprian and the peaks of the Rosengarten.

The descent back the same way to leads to the Refuge Kölnerhptte mountain hut. Alternatively, you can take the tour around the Rosengarten, in which case you should follow trail no. 542 down to the Refuge Gartl Hütte mountain hut, then on to the Refuge Vajolet hut until you come to the Preuss hut at 2,243 m. From here, trail no. 541 leads to the Tschagerjoch. After a long, stony climb up a slightly ascending trail you will come to a fork in the path; trail 550 takes you up to the Tschagerjoch, after which a steep descent over scree land will take you to the Refuge Kölner Hütte mountain hut. From here, you can either descend by chairlift or walk down the forest trail.
