Marmolada South Face (Via Tomasson-Bettega-Zagonel)
The Via Tomasson-Bettega-Zagonel on the South Face of Marmolada (3,343 m) is revered as the Silver Wall (Parete d'Argento) masterwork. Opened on July 1, 1901, by British climber Beatrice Tomasson with legendary Primiero guides Michele Bettega and Bortolo Zagonel, the 800-metre route scales over thirty pitches of compact, polished limestone graded UIAA V, standing as one of the boldest pre-World War I ascents in Europe.

Tactical & Camp Notes
Starting from the Rifugio Onorio Falier in the Ombretta Valley, climbers cross the scree cone to enter the lower chimney systems. The route ascends yellow slabs and deep water-worn grooves, surmounting the great central dihedral and fragile limestone bands before joining the crest near Punta Penia. Sustained concentration is required due to the length of the climb and afternoon thunderstorm hazard.

Frequently Asked Questions: Marmolada South Face (Via Tomasson-Bettega-Zagonel)
What is the Tomasson-Bettega-Zagonel route on the Marmolada South Face?

Who first climbed the Marmolada South Face?
British climber Beatrice Tomasson with legendary Primiero mountain guides Michele Bettega and Bartolo Zagonel.
Why was Beatrice Tomasson's ascent of the Marmolada South Face groundbreaking?
It established a woman at the absolute vanguard of extreme world alpinism, conquering a wall that had rebuffed Europe's finest male climbers for decades.
What is the climbing grade of the Tomasson route?
Graded UIAA IV+ with sections of V-, the route requires masterly route-finding across 30 pitches of sustained limestone slabs, chimneys, and gullies.
How long did the 1901 first ascent take?
Tomasson, Bettega, and Zagonel climbed the entire 1,000-metre vertical wall in a continuous, non-stop push of approximately 21 hours.
Where is the Marmolada South Face located?
Rising above the Val Ombretta in the Trentino and Belluno Dolomites, terminating directly on the summit crest of Punta Penia (3,343 m).
What are the main objective hazards on the route?
Thunderstorms that transform dry limestone slabs into icy torrents, falling rocks dislodged by melting snowfields, and total route disorientation.
What equipment was used during the 1901 ascent?
Simple hemp ropes, nailed boots (tricouni nails), and fewer than a dozen hand-forged iron pitons, emphasizing purest traditional free climbing.
Mountain Ascended
Marmolada
Marmolada (3,343 m / 10,968 ft) is the highest peak in the Dolomites, celebrated as the Queen of the Dolomites. Presiding over the Trentino and Veneto regions of northern Italy, its glaciated northern slopes contrast dramatically with its formidable 800-metre south face (Parete d'Argento). First summited via the north side in 1864 by Paul Grohmann, the mountain later witnessed fierce high-altitude combat during World War I and legendary rock routes by Béatrice Tomasson and Tita Piaz.
