Sasso delle Nove - Sass dals Nü 2904 m

In the Eastern sector of the extensive Sella massif, Boè Subgroup, we find a little known small group of three beautiful peaks enclosing to the North the Vallon basin: from left to right we see Sasso delle Nove 2904 m (Sass dals Nü in ladin), Sass dal Diesc 2916 m, the highest one, even if for a handful of meters, situated in the middle between the other two ones and Piz da Lec de Boe 2911 m, the Northernmost. These fascinating peaks overlook with their stunning East walls the Vallon basin, the adiacent Rifugio Kostner and the Val di Mesdì on the opposite side.

Sass dals Nü in ladin dialect, or Sasso delle Nove in italian, is the Southernmost peak and it's connected to the South with the Boè plateau by a slightly marked saddle, while to the East (Vallon) and to the West (Val de Mesdì) shows two large stunning walls that fall vertically from the broad flat summit ridge. To the North-East the peak projects an overhanging and bold ridge to Forcella del Vallon separating Sass dals Nü from Sass dal Diesc.

All the three peaks offer some very profitable climbing routes, especially on the East wall, whose approach is facilitated by the Boè cable-car and the Vallon chair lift rising from Corvara in Badia, allowing to gain quickly altitude. The summit of Sass dals Nü is easily accessible along the standard route on the South ridge through which runs the Via Ferrata Vallon.



Getting There

The starting point to approach is the village of Corvara , located in the homonymous Val Badia.

Road access to Corvara in Badia

Road access to Corvara in Badia- From Bolzano: follow the Brennero Motorway towards North, exit Bressanone and then follow the Val Pusteria road to Brunico. In Brunico turn to right, following the Val Badia road to Pedraces and La Villa. In La Villa take on the right the road to Corvara.

Approach to Sass dals Nü and Refuge Kostner

- from Corvara in Badia take the cable car "Boe" and the next Vallon chair lift to reach the Vallon Basin. Once at the upper station take the path n. 638, skirting at first Piz da Lec, then Sasso delle Dieci, getting the base of Sass dal Nu, which is separated from Sasso delle Dieci by a narrow and deep rift.

First summiters: the first known ascent was done by Alpine guide P. Pescosta with Joseph Alton and Adolf Gstirner on 1889, august 10th along the South crest - Probably the peak had been previously climbed by local hunters. 

Via Goedeke report

Sass dals Nü East Wall – Via Goedeke report (UIAA scale)

Summit altitude: m 2904
Difficulty: max V UIAA
Route length: 200 m
Exposure: East
First ascent: Richard Goedeke - Suzanne Hornburg 1989, august 8th
Starting point: Refuge Kostner or Corvara in Badia

A very advisable climb with a climbing style mainly inside, as the nearby Castiglioni-Detassis, with which the route Goedeke shares the first pitch. The pegs in place are few, it's useful to integrate with fast protections. The summit is beautiful and wild with vaste views over Sella Group.
