The Briga Sinistra is the easier alternative to the Briga Destra: number 11 on the Finale Outdoor Region map, an intermediate enduro trail. Different, but just as much fun.
After the section shared with the Briga Destra, the trail bends south onto a simpler line. It crosses a tarmac road, then runs down past olive terraces and finishes in Finale. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
