Col de la Colombière, Mountain pass in Le Reposoir, France

The Col de la Colombière is a mountain pass in the Bornes massif of Haute-Savoie, linking the Arve valley at Scionzier with Le Grand-Bornand in the Borne valley. A paved road crosses it, marked by a black sign with white lettering reading "Col de la Colombière" and "altitude 1618 m". The road makes a sharp left bend with a short pale guardrail on the outer edge, bordered by grassy hillsides and scattered dark green shrubs.

The pass was first included in the Tour de France in 1960 and has appeared in the prestigious cycling race over twenty times since then. Its addition transformed it into a key mountain stage for professional cyclists.

The pass road climbs past Le Reposoir, where a charterhouse stood; the village and its monastery lie on the northern approach from Scionzier. The climb is a fixture of amateur cyclosportives such as La Time Megève Mont Blanc and La Grand Bô, so riders on the road are part of the summer scene.

The pass is typically open from May to November, so visitors should expect snow and closures outside these months. It is wise to check local conditions beforehand, especially during shoulder seasons.

The pass sign has long read 1,618 m, but the nearest levelling mark, on the chapel just above and north of the pass, gives 1,615.884 m. IGN's 1:25,000 maps place a spot height of 1,607 m on the road a few metres north-east of the topographic pass, while the 1950 edition and smaller-scale maps give 1,613 m. No geodetic marker stands exactly at the pass.
