From the Triftbahn top station (Sunnige Trift) follow the alpine hiking trail until you reach the Triftwasser stream. Before the bridge over Triftwasser ascend pathless north-eastward. At an altitude of about 1420 m turn right (east) through a ditch and onto the next, forested rib, where a path begins. Follow this up through the forest. From ca. 1480 m the path leads through open terrain with grass and an old moraine; there is a splendid view to perfectly rounded boulders (Chlempenwang). Here the faint path disappears momentarily. At ca. 1720 m you should be on the lookout for the reappearing path in order not to miss the way through to the right (south-east); at one point you walk through an attractive crevice. Afterwards a more distinctive path leads to a small hut at Mälchsteinen (ca. 1910 m). If you love blueberries, allow for more time on this leg as of August! From Mälchsteinen follow a faint path eastward to a rib and continue on this rib past P. 2083 to a rocky ledge, which is easily climbed (ca. 2140 m). After that you will find only a very faint path. Continue to ascend northward, keeping slightly to the right below the rocky projection (ca. 2300 m), where from the right you can pass this rocky structure in a little valley. Then continue on a rib to Sandhibel (2443 m). From here you have a good view of the south-east face of Radlefshoren. Almost in the fall line of the summit (slightly east of it) you distinguish a stripe of rubble, which comes down between slabs. That is where you ascend. The rubble can be fairly well avoided on grass. At the end scramble to the summit over boulders.
