Ferrata del Limbo

Overview

The Ferrata del Limbo, the first via ferrata built in the Biella region and among the pioneers in Piedmont, unfolds along the compact eastern face of Monte Mucrone, towering above the famous Sanctuary of Oropa. Conceived by mountain guide Gianni Lanza and opened in 2001, it offers a route of considerable physical commitment in a rugged, secluded alpine setting. While the progression doesn't present extreme technical difficulties thanks to a dense succession of iron rungs, it is characterized by continuous exposure and a variety of obstacles, weaving through dihedrals, chimneys, vertical slabs, and a short Tibetan bridge. The excursion requires a rather long approach and return, with trails that are not always well-marked, but in favorable weather conditions, the effort is rewarded by an exceptional panoramic view stretching from Monte Rosa to the Matterhorn.

Approach

The route begins at the upper square of the Oropa cable car, accessible from Biella via the SP 144 road. From the top station, follow the signs for "Ferrata del Limbo (sentiero alto)" towards Lago del Mucrone. After skirting the lake on its left (hydrographic) side, a sign indicates the direction for Colle del Limbo and Monte Mucrone Parete E. The trail continues with a moderate slope along the mountainside, sometimes aided by fixed ropes during the summer season, guided by sparse cairns. The final section climbs a debris-filled gully, at the end of which, on the rocky wall to your right, the first metal rungs appear, marking the start of the via ferrata. The approach takes about 1 hour and 15 minutes from the top station (45 minutes from the lake).

Via Ferrata

The equipped route begins with a sequence of rungs up an initial dihedral, tackled on its right side, with some slightly overhanging moves. After overcoming this first section, turn left to ascend a diagonal ledge, traverse left again, and climb vertically up the wall until emerging onto the broad and panoramic Colle del Limbo. This first 120-meter stretch is physically demanding and exposed, but excellently equipped.

Next comes a tall chimney, whose progression is eased by the abundant rungs that outline the path. At the top of the chimney, some boulders require a short climbing move to complete the second section. A short stretch of non-equipped trail leads to the start of the third part, marked by a white sign. Here you climb a beautiful vertical slab, slightly overhanging, before encountering a short three-rope Tibetan bridge. After crossing the bridge, ascend the final wall, traverse left, and reach the end of the equipped route. The Ferrata del Limbo takes about 2 hours from the start, for a total of 3 hours and 15 minutes from the top station.

Descent

From the end of the via ferrata, in a few minutes you reach a large cairn marking the false summit. Continuing over rocky terrain and a faint trail for another quarter of an hour, you arrive at the summit of Monte Mucrone (2335 m). The descent follows trail number 24 towards the Bocchetta del Lago, then turns right towards Lago del Mucrone and the cable car. This return section, where trail markers can be sparse or absent, takes about 1 hour and 30 minutes, bringing the total time for the excursion to about 3 hours and 45 minutes.

Useful Notes

The area is often covered in snow until the end of May, so in the early season it is essential to carefully assess conditions and take appropriate precautions. The sector, though very beautiful, is also frequently subject to cloud cover. Given the sometimes inadequate or outdated signage along the approach and descent trails, it is highly recommended to plan the route by consulting the maps and GPS tracks available for download on the Province of Biella website. For cartography, a reliable reference is the Valli del Monte Rosa map published by 4Land.

For fitter hikers with an early start, in good weather it is theoretically possible to combine the Ferrata Ciao Miki on the same day, also served by the Oropa cable car. Alternatively, descending into the valley, you can consider the Ferrata Nito Staich (short approach), the easier Ferrata della Balma, or the Sentiero Attrezzato dell'Infernone, reachable in about half an hour by car.
