A gentle start up-valley past Malga Canali, a working alpine dairy, then forest path climbs to Rifugio Treviso (1,631 m), one of the oldest huts in the Dolomites, opened in 1897.

From Treviso trail 718 climbs very steeply — 600 m in under two kilometres — to Forcella d'Oltro (2,229 m), your last gateway out of the Pale. Ahead, for the first time, the greener pre-Alps of the Cimonega with Sass de Mura front and centre; the descent drops through forest to the quiet road pass of Passo Cereda.

Right at the start of the day in the Val Canali larches, Rifugio Treviso is the only manned hut on the climb — run by a guide's family, and locally famous for its hot sandwiches. Coffee and a bite here before the long pull up to Forcella d'Oltro.

2Over Forcella d'Oltro
PassForcella d'Oltro (2,094 m)

Above the hut the route settles into the long climb of the day. Path 718 leads first in gentle undulations through forest to the open clearing of Campigol d'Oltro — campigol is the local word for a small upland meadow — and from there the real work begins: roughly two hours of small, patient switchbacks up increasingly rocky, steepening slopes. Forcella means a saddle or notch, and the Forcella d'Oltro at 2,094 m is the slot you are aiming for, wedged between Cima d'Oltro on one side and the jagged Caldrólon peaks on the other. The final pitch up to the gap is notably steep; the saddle, when you reach it, is the high point of the whole stage.

This notch is the watershed of the day in more than one sense. Behind you to the north spreads the southern rampart of the Pale di San Martino, the massif you have been crossing for days. From the forcella the view back is the grand farewell: rank upon rank of pale dolomite towers, the same fossil-reef rock that builds the great summits at the heart of the range — Cima Vezzana at 3,192 m, the highest of the group, and its more famous neighbour Cimon della Pala, the slender horn long nicknamed the "Matterhorn of the Dolomites." Up on the hidden roof of that massif lies the Altopiano delle Pale, a 50-square-kilometre stone desert between 2,500 and 2,700 m, an almost lunar plateau of bare rock that few ranges in the Alps can match. From this saddle you are looking at the outer edge of all of it, one last time.

3First sight of Sass de Mura

ViewSass de Mura (2,547 m), Cimónega group

Stepping through the notch swings the entire horizon around. Where the climb showed you the Pale at your back, the far side of the Forcella d'Oltro opens a completely new panorama to the south and east: out over the Cimónega group, down toward the valleys of the Mis and the Agordino, and across to the rugged country of the Vette Feltrine — the wild, lesser-known Dolomites that the closing stages of the Alta Via 2 will cross on the way to Feltre.

The eye is drawn at once to one great tower. Sass de Mura, 2,547 m, is the highest summit of the Cimónega group, a blunt, powerful peak that anchors this whole quarter of the range. Beside it stands the slimmer blade of Piz di Sagron, the group's second summit, just over a kilometre to the north. Sass de Mura is a serious mountain in its own right: it carries an impressive prominence of nearly 1,180 m, meaning it rises almost that far above the lowest saddle connecting it to anything higher, which is why it dominates the view so completely from here. It sits squarely on the boundary between the provinces of Trentino and Belluno, and its slopes shed water in two directions — west toward the Cismon, east toward the Piave.

4Lunch at Rifugio Cereda 🍴

The stage ends at Passo Cereda, where Rifugio Cereda runs a proper restaurant year-round — Primiero cooking from the family farm. This is the reliable hot meal of the day; there's no staffed hut over the Forcella d'Oltro crossing in between, so it's snacks until here.

5Down to Passo Cereda

From the forcella the trail drops hard, plunging into a gully and dropping back below the tree line. It then undulates over a mix of grassy and rocky terrain along the orographic-left side of Val Canali — the left bank as you face downstream — before the gradient finally relents and the path spills out into the broad grassy meadow of Passo Cereda at 1,369 m, the day's end.

Passo Cereda is a true Alpine col, a saddle that has long linked the Primiero valley with the Mis valley and the road on toward Agordo and the Cordevole. To its north stand the Pale di San Martino, the massif you have just crossed; to its south rises the Cimónega group, the country you are about to enter. The pass is reached by the provincial road that climbs over from Primiero, which is part of its charm and its practicality: after days on the high mountain you arrive somewhere with a road, a saddle of open pasture, and a roof.

Where's the coffee?

Coffee — Rifugio Treviso (1,631 m) — the only manned hut on the climb, right at the start in the Val Canali larches. A coffee and its famous hot sandwich here before the haul up to Forcella d'Oltro.

Lunch — Rifugio Cereda at Passo Cereda (1,369 m) — the real lunch, a proper family restaurant at the end of the stage. Nothing in between over Forcella d'Oltro, so carry a snack for the middle.

Watch out for

No cables, but the Treviso–Oltro climb is relentless and the wooded descent gullies are slippery when wet.

Passo Cereda, Primiero & the Vallalta mercury mines

Historical things to know

Passo Cereda (about 1,361 m) is the saddle that links the Primiero valley around Fiera di Primiero and Tonadico with the Agordino to the east, threading between the southern bastions of the Pale di San Martino and the Cimonega group. For walkers on the Alta Via 2 it is a key crossing and roadhead between the high dolomite country to the north and the wilder Dolomiti Bellunesi to the south. Fiera di Primiero takes its name ("fiera" = fair) from the medieval markets that grew up around its trade in metals and timber.

Primiero's history is inseparable from mining. From the late Middle Ages the valley's silver, copper, iron and lead deposits drew Tyrolean and German miners, and for much of its history the district lay under Habsburg rule as part of Tyrol. The boundary between this Austrian Primiero and the Italian/Venetian lands to the south ran through these mountains — a frontier that acquired grim significance in the First World War, when the front of the "Guerra Bianca" passed close and many valleys were militarised and evacuated.

The most remarkable mining story is the cinnabar (mercury sulphide) deposit of Vallalta, above Sagron Mis at the head of the Mis valley. Mining is documented from the 18th century, with the first concession granted in 1740. The orebody straddled the Austro-Italian frontier: it was worked from two adits a few metres apart — Vallalta on the Italian side and Terrabugio on the Austro-Hungarian side — which for political reasons were kept unconnected until the tunnels were finally joined in 1922.

Vallalta peaked in the 1860s–1870s, when it ranked among the ten most important mercury mines in Europe, employing around 200 people underground. A celebrated condensation furnace, the "Forno di Vallalta," was first fired in 1856 and entered the metallurgical literature. The mine operated, with interruptions, for more than two centuries before closing in 1963; its ruined galleries and furnaces survive as an industrial-heritage and geological site within the park's orbit.

💡 Fun fact

The Dolomites were declared a UNESCO World Heritage Site in 2009 — listed across nine separate mountain groups (including the Pale di San Martino) for both their beauty and their importance to the science of how mountains form.
