Strada Susa-Meana di Susa-Colle delle Finestre-Prà Catinat-Depot di Fenestrelle
A former military road built in 1890 to connect Valle Susa and Val Chisone, it is a world-famous cycling route covering 18.7 km, with an elevation gain of 1,692 metres and 33 hairpin bends. To this day it is still a dirt road for the final 8 km. It is possibly to freely circulate on the road, and it opens on a seasonal basis.
Located almost entirely over 2,000 m above sea level, it is the mainstay of the ridge on the watershed between Valle di Susa and Val Chisone, and with its 19th-century access and connection system of roads and mule tracks (including the Strada del Colle Finestre) it is the main tourist attraction for the integrated use of former military roads. 36 km long, it was almost entirely built in the late 1930s. It is famous for the battle of 19 July 1747 between the French of Louis XV and the Savoy army of Charles Emmanuel III to seize the Assietta ridge and Colle delle Finestre. Motor vehicle circulation is regulated.
Strada Bardonecchia-Rochemolles-Rifugio Scarfiotti (Granges du Fond)-Colle del Sommeiller
Located on the Italian-French border, its highest point is at 3,009 metres on the Colle, making it one of the highest in Europe that can be reached by motor vehicles. 26.5 km long, it has a total elevation gain of about 1,700 metres. At an altitude of 1,625 metres, Rochemolles is the ancient alpine village that was troubled by historic avalanches. Transit is regulated on the Scarfiotti dirt road.
Strade dei Monti della Luna
The area is outstandingly beautiful and of great geological significance, lying between the Chenaillet Massif in France and the Cresta della Luna on Cesana-Claviere. Between 1930 and 1939, it saw the construction of an extremely high number of Alpine Wall works, for which military roads and mule tracks were built, which are still all practicable. The network is closely connected to the adjacent Val Thuras and originates from a complex of no less than 8 former military roads: the Bousson-Lago Nero-Col Bousson, the S.S. 24 - Grange Sagna Longa - Cresta Rascià, the Sagna Longa-Fonte Tana-Lago Nero, the Rocca Clarì-Sagna Longa, the Fonte Tana-Chabaud, the Ruilles-Chabaud-Colle Begino, the Chabaud-Giaissez, the Bousson-Rouilles, the Rouilles-Ponte Ciatagnera. In the Monti della Luna area alone, the various itineraries add up to a total of about 60 km of natural roads, which can be covered on foot, by MTB and off-road vehicles.
Strada Fenil-Pramand-Foëns-Jafferau with the Galleria Seguret “dei saraceni”
Built from 1890 onwards to connect the Fenil, Pramand, Föens and Jafferau batteries, built to defend the basin of Bardonecchia. The real gem is the spectacular Galleria del Seguret or del Pramand, also known as the " Galleria dei Saraceni" (Saracen Tunnel), a good 876 metres long and dug into the rock in a curve, under the limestone spires of Monte Seguret, in between the two World Wars. It can be covered on foot, by MTB and by regulated off-road vehicles.
Strada della Valle Argentera
It is the virtually unchanged military road route built in 1910 to reach several fortifications that are still visible. Although the valley had no direct road outlets, it was crossed by salt smugglers. This is a mixed-use road, with paid access for a limited number of motor vehicles during the summer months.
