Wilden Hinterbergl (3288 m) via Berglas crossing and north face

(1) From the Franz-Senn-Hütte, follow path no. 131 along the Alpeinerbach. The approximately 2.3 km long path through the glacier-formed high valley is easy and runs, except for the short terrain step - the "Höllenrachen" - very flat towards the valley end. Where the path branches, follow the right trail marked "old" on a rock. This trail leads us in some switchbacks without difficulty up to the striking lateral moraine of the Alpeiner Ferner (a remnant of the glacier's state in 1850).

(2) Where we first reach the ridge of the lateral moraine (about 2400 m), we leave the "old" path that continues over the moraine ridge to the right. We now follow the noticeably narrower and more sparsely marked trail north towards the Berglastal. We reach a remote high valley and the foothills of the orographically right moraine of the Berglasferner. This moraine ridge is where the trail runs, leading to the Berglasferner from which we will descend. Our trail to the Berglas crossing branches right here and leads us to the northern lateral moraine of the Berglasferner and further up over its ridge.

(3) The trail ends at 2660 m where the lateral moraine meets the steep slope dropping from the cirque floor below the Berglas crossing. Without a path, go up this slope about 100 vertical meters to the flat cirque floor, then turn right towards the stream of the Berglastal. The snow or ice tongue of the Berglas crossing is clearly visible. We reach its lower end by climbing blocks on the right of the watercourse out of the cirque hollow and only shortly below the ice field switch back to the left. Here, right at the edge of the narrow glacier tongue, you can put on harness, helmet, and crampons. The Berglas crossing itself is a glacier slope up to 35° steep, leading after about 100 vertical meters onto the Lisenser Ferner. Experienced ice climbers will ascend without a rope; for beginners or less experienced climbers, a rope safety may be advisable depending on current conditions.

(4) After the Berglas crossing, we reach the Lisenser Ferner at around 3000 m. We now head directly towards the clearly visible north face of the Wilden Hinterbergl and climb as far as possible in glacier rope teams over the foot of the north face to the bergschrund. The area just below the bergschrund is generally ideal to switch into climbing rope teams and put on crampons (if taken off after the Berglas crossing). The north face of the Wilden Hinterbergl reaches about 50° at its steepest point, extends approximately 100 vertical meters (3 rope lengths). The ideal line for the ascent is approximately in the middle of the face also to minimize risk of rockfall. The face leads to the flat and extensive glacier ridge over which we easily and within a few minutes reach the main summit.

(5) On the descent via the Berglasferner, first head towards the Turmscharte (3126 m). About 200 m before the notch, turn left into the now somewhat steeper part of the Berglasferner. Current conditions on the Berglasferner determine the correct path - in our case this was the far right area (in terms of descent). Lots of slush snow allowed relatively easy and quick progress in glacier rope teams here. Only in the lower section was the glacier bare, requiring detours around crevasses. At the glacier end, continue without a path over scree and block terrain. Always keep to the clearly visible moraine ridge where cairns mark the start of a small trail leading down the said moraine ridge to the previously known ascent path. Follow this back to the Franz-Senn-Hütte.
