The Bocchetta Pass, from the top of the scree above
Continuation towards Punta Valnera
From the Bocchetta Pass it takes about an hour to reach Punta Valnera (2754m), following two different routes of varying difficulty.
- The first (in red in the map below) follows the continuation of Trail 4 along the ridge leading to the point: definitely not recommended for those with vertigo, as there are 3 easy climbing passages, but one of them is quite exposed (in red in the map below).
- The second (in yellow in the map below), without any technical difficulty, leaves the ridge after a few meters, descending on the side of the slope on the Val D’Ayas side, and continues practically straight until it crosses the Val d’Ayas Trail 6A, which climbs from the Estoul Lakes. Trail 6A points directly to Colletto di Valnera (2681m), from which, in a very short time, you will reach Punta Valnera (2754m).
The map also shows (again in yellow) the possible alternative return route that, from the Colletto di Valnera, descends to the Colle di Valnera from which it is then possible to return to the valley via Trail 5.

The connections to Punta Valnera
The first section is shared: continuing northward from the Eclou vent, climb up the short scree slope following the obvious tracks until you pass the rocky outcrop that allows you to look out again along the east side of the mountain.

Past the scree, the ridge towards Punta Valnera
You pass a helicopter landing pad, and it is shortly after that the two paths fork.

The helicopter platform
1) Punta Valnera via Colletto Valnera
After less than fifty meters from the helicopter pad you will see on the left an obvious trail, with yellow bolts, that leaves the ridge and points toward the distant notch. To the right, however, Trail 4 continues along the string of wooden avalanche guards.
In the photo below you can clearly see one of the bolts to follow, just off the route along the right ridge; the distant Valnera col and punta Valnera, on the right.
Circled in red are one of the bolts to follow, the collar on the left and Punta Valnera on the right
The trail traces in this first section are very shaky, there are sparse markers and a few cairns here and there: when in doubt continue to proceed keeping horizontal, without losing too much altitude. One must continue in this way until crossing the very obvious tracks of the Ayas Valley Trail 6A, which climbs vertically from the Estoul Lakes.

Trail 6A climbs up to the Valnera Colletto
In less than a hundred meters of elevation gain, you will reach the vent (2681m)…

… and with a final scramble over friable terrain you reach Punta Valnera (2754m).
2) Punta Valnera along the ridge (trail 4)
From the helicopter platform, continue straight past the avalanche guards until they end.

The path climbs next to avalanche guards
Continue to climb along the bump on which you are climbing, following vague tracks but mostly pointing to the cairns that here and there indicate the way.

One of the cairns to follow
When you reach the end of the hump, you have to go around the rocky antecedent that precedes a small notch, beyond which the rocky ridge to the summit starts. There is only one tricky spot here, where if you are fooled by the trail markings you would attempt to climb in adherence by cutting through a wide but steep flat rock: you actually manage to go around it on the left, with a few exposed but certainly less risky steps.

You don’t have to go up directly, you go around to the right
Past the anticima, you can see the entire ridge to Punta Valnera. The route is less dangerous than it may appear from this point.

The ridge appears after the summit
There are three or four points where climbing is needed, but it is always very easy and safe climbing because the rock is never vertical: only one is slightly exposed, but it is overcome with a few elementary movements.

One of the easy climbing sections
Also among the points to be overcome is a step of about two meters downhill, over which one is able to “unclimb” without problems or danger.

The step you descend disarramping
The last section is directly on the ridge, which is quite aerial but never dizzying: it reaches the summit directly without any additional steps.
From Punta Valnera, the view sweeps from south to north over the entire range that continues beyond the Eclou vent to Mont Nery, over the Estoul Lakes, over Mount Bieteron beyond the Valfredda Collet to the west, over the Corno Bussola to the northwest, and over Punta Valfredda to the north.

Punta Valnera, 2754m
1. Start and finish
Trail 4 starts from Staller Falls in Greshmatto, the elevation is 1380m.
See on Google Maps.
There are several parking spots along the road below the Staller Waterfall. You can also leave your car at the large parking lot by Lake Gover and continue to the waterfall by taking the Queen’s Trail to Savoia Castle.
The arrival location is at the Bocchetta di Eclou. The altitude is 2526m.
See on Google Maps.
2. The route
The trail starts near the famous Staller Stream Waterfall, which is located along Queen’s Trail 15.
From the road, the signs for trail 4: climb up to the waterfall
As soon as you arrive at the waterfall, the trail begins to your right.
The start of trail 4 next to the waterfall
It begins to climb steeply and steeply in the shady larch forest, at first skirting the waterfall and then moving to the right. You pass a ruin and start climbing again, always occasionally moving to the right: it is after you have overcome about 400 meters of elevation gain that you come out of the trees into a wide clearing where you will find ruins of Alpe Roncké, at 1878m…
Alpe Ronché, 1878m
… and the intersection with the 1W Walserwerg trail.
The intersection with the 1W trail at 1878m
Continue for about fifty meters along the trail to the left until an obvious fork in the trail indicates a branch to Trail 4, upward. At the bottom, however, continue along the 1W trail.
The detour from trail 1W to trail 4
From here we gradually leave the shelter of the trees: the path climbs at a gentler gradient than the first section but still sustained, crossing large expanses of dense wild rhododendron bushes that hide the tributary rivulets of the Staller stream.
In 2021, dense rhododendrons that until the previous year were obstructing the path were mowed down
At 2000m, shortly after fording to the left a stream, at a yellow vignette…
The sign a few meters from Alpe Staller (2000m)
…you can see a vague trail that leaves the main path to the left: if you follow it for a few meters, you will overlook the other side until you seeAlpe Staller, which otherwise would always remain hidden.
Alpe Staller, 2000m
Continuing on the main trail, ford the stream back to the right and continue the ascent moving gradually up the right side of the gorge.
You go up the right side of the valley
After a change of slope at 2217 meters,Alpe Gruebe (2280m) finally appears, in the middle of a wide basin dominated on the left by Mt. Ciosè. The Bocchetta Pass is visible on the far right of the final ridge.
2217m, Alpe Gruebe and the final basin appear.
You get to Alpe Gruebe via two different paths, one to the left and the other to the right (yes, there are two different sets of yellow vignettes, probably from different eras). I always follow the one on the right, which goes up keeping to the edge between the meadow and the boulders on the right: there are numerous bolts and cairns that make the route quite intuitive.
Alpe Gruebe (2280m): the vent is the first opening from the right
The trail turns behind Gruebe Alp on the right, and heads left toward a stream whose sound can be heard. You climb by keeping to the left at first, ascending to the rock face above, and then making a handful of wide turns when you are in the final quarter of the ascent. Below is the detail of the route, from Alpe Gruebe (lower right) to the vent (upper left).
Gruebe to the vent
This is undoubtedly the most strenuous section of the trail because it is decidedly steep.
the steep final stretch to the vent
It is not without breathing a sigh of relief that we finally reach the pass of the Eclou vent (2522m).

3) From Punta Valnera, return from Colle Valnera.
Instead of taking the outward route, you can return to the valley along Trail 5, descending to Valnera Pass (2675m) , which is located north of Punta Valnera.
The descent to Colle Valnera
You have to descend to the Valnera Pass, and instead of returning to the Bocchetta di Eclou by turning south (left coming down from the point), you have to take the opposite direction (north, right coming down from the point). You descend into the basin below, and come following the trail to a fork (indicated by clear yellow markers) that points in the direction of 5C, which descends, on the left, to the Arp hut in Val D’Ayas. Instead, one must continue to the right along Trail 5 (of the Ayas Valley), which in about 20 minutes climbs about 50m in elevation until it reaches the Valnera Pass (2676m) .

From the pass, you can then return to Gressoney Saint-Jean along Trail 5 (from Gressoney Golf Course, the end point of Trail 5, to the Staller Waterfall, add about one kilometer).
This is the map of the trail, according to the SCT Trail Cadastre of the Aosta Valley.
3. Personal excursions
16/6/2021
I hiked this trail in June 2021 by taking precisely the route described on this page, that is, ascending to Bocchetta di Eclou, continuing to Punta Valnera, and descending to Colle di Valnera from where I returned to the village via Trail 5.
Of note on this day:
