Mountain

Aiguille de Rochefort is a mountain in the Mont Blanc massif (France). Its summit stands 4,001 m above sea level. Its prominence — how far it rises above the highest saddle linking it to a taller summit — is 106 m.

From the lowest point within 5 km (1,373 m), it rises 2,628 m. The steepest side is the south face: 46° on average over the first kilometre. In places the ground near the top reaches 64° — terrain for climbers, not walkers.

The nearest town is Courmayeur, 7 km away at 1,224 m: 2,777 m below the summit.

Scores

Aiguille de Rochefort for skiers and climbers

Hiking & mountaineering

9.4/10

Difficulty to the top

Alpine climb

Most path sections around the top are T4 on the SAC hiking scale. Glaciers around the top.

Indicative only — never a safety assessment. Conditions change: ask local guides and check the forecast.

How these scores are made

Ski (where OpenStreetMap has skiing within 12 km): up to 4 points for the length of downhill runs (300 km or more = 4), 1.5 for the number of lifts (40+), 1.5 for the vertical between lift stations (1,500 m) and 3 for the snow season — a month counts when the estimated mean temperature at the height of the ski area is −1 °C or lower and snow falls or lies there (NASA POWER, 2001–2020). Hiking & mountaineering: up to 2.5 for waymarked routes and paths, 1.5 for huts, 2 for the ascent from the valley (2,000 m), 1.5 for prominence (3,000 m), 1.5 for the season (months with summit afternoons above −5 °C) and 1 for via ferratas, climbing and glaciers. OpenStreetMap is built by volunteers: where few things are mapped, a score can be lower than reality.
