Les Tourniquets is the name given to the distinctive series of twists and turns (hairpin bends, or cutbacks) on the RD1 county road to cross the rocky barrier formed by the Jurassic limestone which closes the Sasse basin-valley to the north.
This road has replaced the mule track which winds along the other bank of Eau Amère and which predates it: it already appears on the Cassini map in the 18th century.
This road connects the Bayons valley, its forests and its mountain pastures with the Turriers basin-valley and also with the Blanche valley and town of Seyne via the Garcinets mountain-pass,
This road, the RD1, has primarily replaced the Chemin de Grande Communication (the main route, thoroughfare) from Seyne to Apt (1885), itself the heir to the DR17 road of 1813.
It should be noted that the village of Bayons is only accessible by this one road, which passes by Les Tourniquets as well as the narrow Bayons gorge, located at the lower-level of the road.
