Can you drive through Col d'Allos?

Set high in the Southern Alps, the road to the summit is totally paved in very bad conditions and very challenging with numerous hairpins. The road surface is quite bumpy. It’s small and intimidating. It’s called D908. Drivers of caravans and trucks need to be very careful. Not for the faint hearted driver as there are some serious drop offs. Like many of the passes in this area it owes its reason for being to military strategies, involving the defense from Italian and German attacks. Allos opened in 1891, 22 years before another option to cross this ridge via the Col de la Cayolle was added.

The pass is 39.1 km (24.29 miles) long, running south-north from Colmars (or Colmars-les-Alpes) to Barcelonnette. The pass is very steep, hitting a 12.5% of maximum gradient.

Located to the west of the Parc National du Mercantour, the little sinuous road through the pass is closed from October to July. It’s one of the most popular climbs in the Tour de France. In July and August it is reserved for bicycles on Friday mornings.
