Zube pass (2,871 m), trail 4B

From the Gabiet refuge to Zube pass
(you can continue to the Red Horn/Rothòre).

Lyskamm and Vincent Pyramid from the Rothòre

Trail 4B starts at the Gabiet refuge (2,364 m) and ends at Zube pass (2,871 m). It is 3,240 meters long, and the total elevation gain is 513 meters.
The estimated time for the ascent is 1 hour and 34 minutes. The trail is rated of difficulty E.

For the first section, the trail runs along the same route as TRAIL 6 , which leads to Olen pass.

Zube Pass is located at the end of the first little valley that opens up on the right (east-southeast), coming up from Gabiet, before reaching Col d’Olen. After passing the short access step, the short gully is rather narrow and often, even in summer, a small snowfield covers parts of it.

Zube Pass and Col d’Olen are separated by the Corno Rosso/Rothòre, 3023m, a fun summit that can be reached directly from Zube Pass by following vague trail markers and cairns. The view from the Corno Rosso is spectacular, in addition to being in the front row on the Vincent Pyramid and the surrounding 4000-meter peaks, many notable points in this area of the upper valley are clearly visible: Blue Lake, Punta Telcio, Alta Luce, Colle Salza, Testa Grigia, Rothorn, the Quintino Sella huts, Città di Mantova, Capanna Gnifetti, and so on.

Technically, the trail to Zube Pass presents no difficulty.
On the other hand, from the Zube Pass to the Red Horn, since there is no continuously marked trail, it is necessary to be able to “read the terrain” and scout out the route indicated by cairns and bolts scattered on the rocks. The only technical difficulty is at the very end, as the summit is on a group of flat rocks over which you have to climb.

A curiosity: in the Walser language, “zubio” means “pee,” and it appears that the place name refers to the presence of numerous waterfalls in the area (from Wikipedia).

2. The route

After exiting the gondola, walk back up the dirt road for a very short distance until you reach the Adler’s Nest mountain hut (formerly Rifugio del Lys): follow the signs for trail 6, since trail 4B is not marked among the many waymarks at the hut.

The marker at Adler’s Nest

Continue climbing towards the Albergo del Ponte hotel: once you reach the hotel, go around the large rock on the right-hand side and take the path that initially climbs to the right.

It’s easy to get confused in this area because there are several short trails that intersect with one another, but it’s very easy to stay on track: if you see a sign painted on the rocks or a traditional waymark at a fork in the trail, always follow the direction toward trails 6 or 4B. Otherwise, choose the direction leading north, that is, in the direction of the winter ski slope/gondola pylons.

Shortly after leaving the Del Ponte Hotel, the trail climbs for a fair distance “to the right”: don’t worry, though, because you’ll soon come to a fork marked 4B/6, which finally takes you “to the left.”

The crossroads just after the Albergo Del Ponte

After passing through a cluster of gigantic boulders, you’ll come to a small pond: at this point, there’s a waymark that—for the first time since Gabiet—indicates trail 4B. Trail 4B crosses the small lake and climbs along the right bank; however, it’s not a problem if you stay on the left bank of the lake, because further up, trails 4B and 6 merge along the ski run anyway.

Signs for trail 4B near the small lake

In any case, don’t get too much trouble: just keep climbing northeast, parallel to the ski slope/gondola pylons, always staying at the right edge of the slope. It can be clearly seen from this image produced thanks to Google Earth.

The path after Albergo Del Ponte

We continue to climb on the poorly marked trail (since, given the wide dirt road available, everyone walks where they think is most comfortable). After passing a stone hovel, arriving at about 2750m, you will come to a small valley that rises to the right behind a huge boulder. There are some faint red arrows on the ground.

It is at this point that we leave the wide road and cut right, toward the small valley that will take us to Zube Pass. After passing the boulder, the trail climbs the short but steep valley step with slippery terrain, which is overcome with marked turns.

Above the step the slope softens, and we continue up the narrow gully within which, suddenly, we seem to plunge into another planet, so jarring is the sudden loneliness in comparison with the busy piston defaced by the pylons of the gondola we have just left.

Climbing along the little valley of Zube

It contours a small stream in the first section: passing a series of small plateaus and, often in summer, a small snowfield, one arrives without much difficulty at Zube Pass (2871m).

Continuation to the Red Horn/Rothòre

From Zube Pass, the Red Horn is one of the rocky cliffs seen to the left. The trail is quite evanescent at first, you have to look for marked tracks on the ground, cairns and colored markers: it is, however, “all to the right,” sticking fairly close to the mountain ridge.

Starting from Zube, head toward the cairns visible on the left side of the hill behind the pass, not toward the cairns visible on the top of the hill. You have to go around the hill on the left; don’t go over it from above.

The following picture of the trail, taken from Google Earth, helps you realize the direction you need to keep:

The route is not technically challenging: when moving over purely rocky terrain, cairns are very frequent and it becomes easier to follow the trail. Still keeping to the right, you will soon reach the vicinity of the summit, where you will encounter the only technical difficulty of the route, since the summit cairns (there are more than one) are at the top of rocky clusters to climb over.

The rocks above which the summit of Rothòre is located.

The funny thing is that none of the cairns are obviously higher than the others, so you will end up scouring them all trying to figure out which is the real peak (in my opinion, however, the highest is the one on the left).

Lyskamm and Vincent Pyramid from the Rothòre

From the Rothòre, 3023m, there is a truly 360-degree panorama, as wherever you turn your gaze you will encounter a remarkable vantage point. Clockwise, starting from the southwest, we see the plateau surrounded by Testa Grigia, Bec Forcü and Rothorn, immediately after the Rothorn valley with the Salero lakes, then gaze along the ridge after the Bettaforca pass and catch a glimpse of the Quintino Sella refuge, just below the Blue Lake, Punta Telcio, the plateau with the refuge Orestes Hütte, above which the Colle Salza, the Alta Luce, the Città di Mantova hut, the Capanna Gnifetti can be distinguished in sequence… it is really worth taking binoculars with you, or the most powerful telephoto lens: they certainly won’t stay in your backpack at this point.

In this other image from Google Earth you can see the complete route starting from Albergo Del Ponte, with highlights.
