Route description The Tierbergli via ferrata (K4) climbs the rocky flank below the Tierberglihütte above Steingletscher, with the Steinlimigletscher providing a dramatic high-alpine backdrop throughout. The route is uneven in difficulty: a first section of mostly K2/K3 climbing leads to a stout, slightly overhanging crux, while the second section is generally harder (K3) but without a single standout passage. Good weather is essential, since the slabby rock becomes very slippery when wet or snow-covered.

From Steingletscher (1865m) follow the white-red-white marked path, or the access road, up to the Umpol car park (about 2100m), from where the via ferrata starts nearby. Driving directly to Umpol on the toll road shortens the approach considerably.

From the Umpol car park, the first cable begins at the foot of the rock (~2100m) and eases gently across glacier-smoothed slabs into the east flank of the Tierbergli, crossing a gully above its base. The terrain steepens gradually with iron rungs aiding sparse footholds, leading to the crux: a slightly overhanging wall tackled from the right via rungs onto a ledge, an exposed traverse, and a strenuous pull (remember to re-clip) into easier ground. Cables then lead over stepped rock to a short, strenuous rise with awkwardly placed protection, before angling left onto a large scree terrace at roughly half height (~2380m), where the hut path crosses. A sign directs left to a second via ferrata start marked in yellow-red, from where cables climb steep, exposed rock, pass a small resting knoll, and reach a blocky slope. After about 50m of loose terrain, a further 30m climbing section leads back into scree, followed by one more protected pitch up a steep slab with artificial holds to the exit on a shoulder (~2610m). From there, follow red markings and cairns diagonally uphill (southwest) to reach the Tierberglihütte.
