An interesting, picturesque road descent short-cut - reducing the main route of section '3 VV-Tende - Ville Vieille to Col de Tende / Colle di Tenda' by approximately half a day. Skips the rough Strada Cannoni section following the Col Sampeyre. A good one for anyone on slim road tyres.
A long and more remote section of the Via del Sale - a stunning military strada and old trade route passing the Refuge Don Barbera on the way to Dalmas. Then onto the big climb to the Fort de la Forca and finishing at the Col de Turini. Includes unlisted OPT_3 - sign-ups for Sept 6th via TNR site get the additional section.
The longest section, starting on tarmac over the main route's high point at the Col Agnel / Colle dell'Agnello, then onto the Strada Cannoni, a high-altitude strada with an optional way down (OPT_1) before reaching Dronero and another high strada with a road option for the climb up (OPT_2).
