Stelvio
The Alps at their most vertical — Ortles and Cevedale over the 48 hairpins of the Stelvio road, with the White War's frozen front line melting out of the glaciers.
Created in 1935 as the fourth of Italy's historic parks and still among its largest, the Stelvio wraps the Ortles-Cevedale group — the mightiest massif wholly inside Italian borders. König Ortler, 3,905 metres, lords over the South Tyrolean side with the ice pyramid of Gran Zebrù beside it; Cevedale anchors the southern glaciers, including the Forni, Italy's largest valley glacier, whose retreat the hut wardens can date year by year like tree rings. Since 2016 the park has been run as one territory by three administrations — Lombardy and the autonomous provinces of Trento and Bolzano — and together with the adjoining Swiss National Park and the Adamello parks it forms the largest protected complex in the Alps.
Its most famous line is a road. The Stelvio pass, 2,757 metres, was blasted through by Habsburg engineers in the 1820s to link Vienna to Milan, and its 48 numbered hairpins out of Prad have become cycling's most photographed suffering — the Giro d'Italia's recurring Cima Coppi, and on the annual car-free Bike Day a pilgrimage of thousands. The heights above the road hold darker engineering: this was the White War's highest front, where from 1915 to 1918 Austrians and Italians fought at almost 4,000 metres, and the shrinking ice now releases their cableway anchors, barracks timber and sometimes their dead — an archive melting out of the Ortler front a century late.
The valleys are the park's living rooms, each with a temperament: Val Zebrù, a private-feeling trench under Gran Zebrù where September evenings belong to bugling red deer; Val Martello, strawberry fields below Cevedale approaches; Val di Rabbi's larch meadows and hay barns on the quiet Trentino side; Valfurva and Santa Caterina above Bormio's thermal old town. Ibex hold the crags, the park's red-deer herds are the biggest management question in the Alps, and bearded vultures — reintroduced here in one of Europe's founding release programmes — patrol the whole massif again.
What's worth knowing before you go
Bormio (bus from Tirano's rail terminus) serves the Lombard side; Prato allo Stelvio and the mountaineering village of Solda serve the north via Merano. The pass road opens roughly late May to early November; huts — Branca at the Forni, Pizzini, Quinto Alpini — run mid-June to late September. Glacier travel here is real mountaineering; the valley trails are not, and the Val Zebrù walk is the best effort-to-grandeur ratio in the park.
The connoisseur's date is the September deer rut in Val Zebrù at dawn — or Bike Day, once a summer, when the 48 hairpins carry nothing but breathing and freehubs and the mountain gets its road back.
