Passy
Passy doesn't announce itself. It sprawls across 80 square kilometres of the Mont Blanc massif — from the valley floor at 500 metres up to nearly 2,900 — taking in a dozen distinct hamlets, a plateau built for the sick, a factory town, and slopes that sent riders into the 2023 Tour de France time trial. The sculpture route alone runs 15 kilometres, threading contemporary works through the pines between the plain and Plaine-Joux.
What holds all of it together is altitude and air. In the 1920s, the Plateau d'Assy drew tuberculosis patients precisely because the exposure was so clean and the southern face caught so much sun. That same quality of light still defines the place — sharp, high, unhurried.
💛 What travellers fall for
People who come back tend to do the Nant Bordon footbridge early, before the walking groups arrive — 160 metres of Himalayan-style suspension, 20 metres above the watercourse, and genuinely vertiginous. Then Notre-Dame-de-Toute-Grâce for the Chagall and Matisse work inside, which you won't see coming from the plain exterior. The Jardin des Cimes rewards slow movement.

How Passy came to be
Roman presence in the first century left traces in local place names, and by the late 12th or early 13th century Passy was the seat of the Châtellenie de Charousse, a fortified stronghold in the County of Geneva's defensive network. The castle had crumbled by the 1400s. Passy passed to France with all of Savoie in April 1860, when 99.8 percent of the population voted yes in the plebiscite.
Two later chapters reshaped the commune entirely. In 1895, the Usine de Chedde opened in the valley — by the turn of the century it was the largest factory in Haute-Savoie, running at over 10,000 horsepower. Then, from the 1920s onward, the Plateau d'Assy filled with sanatoriums: Praz-Coutant opened in 1924, Sancellemoz followed in 1931. The plateau's sacred art culminated in Notre-Dame-de-Toute-Grâce in 1950. In April 1970, a landslide struck the Roc des Fiz children's sanatorium, killing 71 people, 56 of them children — one of the deadliest such disasters in 20th-century France.

When to go
Summer (June to August) sits between 20 and 26°C and July delivers around 275 hours of sunshine — the clearest window for both walking and the outdoor sculpture route. Winter is cold and snow-reliable at elevation, but the plateau's south-facing orientation means the light is rarely absent for long.
