A short round trip route that follows unpaved roads uphill until it reaches Piron. For the downhill portion, at La Comba, we suggest a detour on a small unmarked path, a decidedly more interesting route than the "official" one.
From SS 21, uphill from the houses of Aisone (840 m), turn off on the road leading up to Case Piron. Pass the trail leading down to the Aisone caves (which you will follow back up to the road on the return leg) and continue on the road until you reach Case Piron (1031 m, 35 minutes from Aisone). The route proceeds midslope, following an old mule track in the Valletta del Rio Borbone. Shortly before reaching the ridge marking the watershed, the trail dips downward to the left towards Castellar delle Vigne.A flat stretch of trail cuts across the slope to the hamlet of Baile (1040 m, 25 minutes from Case Piron).
{From Baile it is a short walk to Castellar delle Vigne (1035 m), where a marked path leds down to La Comba.}
In Baile, walk south among the houses until you reach the last one. An unmarked path heads east and winds down through the woods until it reaches a small clearing in La Comba (900 m, 15 minutes from Baile).Here there are still some buildings with straw roofs at the foot of the characteristic rock outcroppings.For a brief tract, the route follows an unpaved road leading downvalley, but leaves it for a path to the left, near an electrical pylon. The path runs along a sun-drenched slope, following the undulating foot of the limestone cliffs, along which open the mouths of several natural caves, some easily accessible, known as the Aisone caves (884 m, 20 minutes from La Comba to the farthest cave).The last portion of the route rejoins the unpaved road seen at the start to return to Case Piron.

The route initially passes through small hamlets, some of whose buildings are still roofed over with rye hay, then skirts several natural caves inhabited by humans in neolithic times. Its excellent exposure to sunlight makes it a perfect excursion in spring and fall.
From Borgo San Dalmazzo, up Valle Stura to Aisone. The excursion begins just past the last houses, at the fork (marked with road signs) for Piron.
