Starting point: Rum railway station (568 m)
Access: From the starting point, where you can arrive by train or park the car in front of the Rumer Hof hotel, the path turns north straight into the village of Rum. We follow Bahnhofstraße until the intersection where we turn right into Schulstraße and after 200m left into Langer Graben road. We follow this road through the village of Rum until it meets Finkenberg road. At the end of Finkenberg road we notice the signpost Vintlalm-Pfeishütte. We follow the nice forest path number 2/3 and after half an hour reach a spring where we can refill drinking water. After another 10 min we arrive at Garzanhof farm, where the path turns right (all nicely signposted). The path winds through the forest. The next junction is at Kiechelberg junction, where path number 3 branches right to Thaurer Alm, we go left on the forest road, where after a few meters our path branches right (number 2). Then follows a steep 500 elevation meters, through the forest, across Garzanmahd pasture to Vintlalm hut (1568m). From the hut onwards the path winds through bushes and shrubs to Kreuzjöchl saddle (2121m). The path is signposted with 2.5h. To our left branches the path to Rumer Spitze; ahead of us, towards the northeast, we see Kleine Stempeljochspitze. Straight north we see the Sonntagskar cirque.
I - Hintere Bachofenspitze: Below us is Pfeishütte hut, descend there (approx. 200 elevation meters). A little below the hut branches the path to Sonntagskar cirque - signpost Sonntagskarspitze (2.5h), Hintere Bachofenspitze (2.5h). First the path winds through rhododendrons until we step to the place from where the view into Sonntagskar cirque opens and paths branch to Sonntagkarspitze or Hintere Bachofenspitze. We follow the marked pathless terrain

. There are enough markers, but no trodden path. The path winds over grass northwards until we reach scree, over which we must painfully step on a well visible track to the wall. The entrance to the wall is marked with a large red mark on the rock. The path through the wall is not secured, and has spots where you need to handle climbing up to grade 2. When we step to the top of the wall, we stand on the ridge between Roßkopf (towards south) and Hintere Bachofenspitze (towards north). From here only 100 elevation meters to the summit (2668m). The summit is isolated, as the summit book there is from 2004 and far from full. The path is almost entirely in the sun and no water on this section. I descend the same path to Pfeishütte.
II - Kleine Stempeljochspitze: From Pfeishütte winds a highway to Stempeljoch saddle. From there leads a path on the south side through grass to the summit Kleine Stempeljochspitze (2529m). The path is not always clearly visible, but terrain doesn't allow getting lost. In the rocky summit part markers are again very good. Also on this path no water and path exposed to sun all the time. I descend the same path to Stempeljoch saddle, where it is possible to cross on an unmarked path to Kreuzjöchl notch and from there descend to Neu Rum.
Neu Rum (568m) - Kreuzjöchl (2121m) - Pfeishütte (1922m) - Hintere Bachofenspitze (2668m) - Pfeishütte (1922m) - Kleine Stempeljochspitze (2529m) - Stempeljoch (2215m) - Kreuzjöchl (2121m) - Neu Rum (568m).
The route, in terms of elevation gain (3000m), length (~27km), as well as external influences (sun, no water), is a pleasure for every mountain lover
