Col de la Bonette, Mountain pass at 2715 meters in Saint-Dalmas-le-Selvage, France.

Col de la Bonette is a mountain pass at 2,715 metres in the French Alps, between the Cime de la Bonette (2,860 m) and the Cime des Trois Serrières (2,753 m). The paved road links Jausiers in the Ubaye valley with Saint-Étienne-de-Tinée in the Tinée valley, crossing the Col de Restefond (2,680 m) just below the pass. From the pass, a two-kilometre loop road circles the Cime de la Bonette and reaches 2,802 metres.

The pass was developed during the 20th century with military fortifications to protect the French-Italian border in this alpine region. This strategic role shaped its development as a key transport corridor across the mountains.

The Tour de France has crossed the pass five times, with the mountain classification always taken at the 2,802 m ring road around the Cime de la Bonette. In 1962 and 1964 the Spaniard Federico Bahamontes was first over the top, in 1993 the Briton Robert Millar, and in 2008 the South African John-Lee Augustyn, who crashed on the descent and left victory to Cyril Dessel. A stele of Notre-Dame du Très Haut from 1963 stands just below the pass on the southern climb.

The pass road is closed in winter, as is the road over the Col de la Bonette; the climb from Jausiers runs 22.2 km at 6.7%, the one from Saint-Étienne-de-Tinée 24.4 km at 6.4%. The last kilometres before the pass are gentler, but the final 800 metres up to the 2,802 m loop reach gradients of 15%. The descent has many hairpin bends.

A short side road climbs to Cime de la Bonette at 2,802 meters (9,193 feet), making it the highest paved road in the European Alps. This detour rewards drivers who take it with an even broader view across the surrounding mountains and valleys.
