Tanello river is short with a flat flowing from the Saccarello crest- Fronté to the Tanaro’s mouth.

  • From Ponte di Nava along the route 28, it must turn into the road that leads in Viozene and Upega (town of Briga Alta, CN).
  • After 5 Km along this road, it reachs the deviation to Val Tanarello where you can park your car. It pass through the stream by a little bridge then it starts to climb back up.
  • Further on there is another bridge, Schiarante near an amazing promenade that joins Nava to Upega. At this point of our journey it necessary take a visit to the Cornarea Den, an extraordinary example of natural cavity particularly interesting in a palaeontologic view.
  • Passed on the Schiarante bridge, it takes a little path that lead into the woods above the Tanarello right side.
  • After a short rise, it gets to a fork and taking the left way it arrives at the gate ofthe CornareaDen (1038 m.), the only cave in this spot where lived men in the Bronze Age.


Cornarea Den

In this cave it has been found a lot of archaeological findings more or less around 1000 – 900 B. C. as ceramics, grindstones, green stone hatchets, blades and flint scrapers, sea-shell necklaces and ornamental glasses. The excavations found holes for tent poles and hearths with scraps of sheep bones, signs of pastoral life. Next the ancient transhumance routes, the cave was a refuge for those shepherds that in springtime took their cattle in the high meadows.

The Den measures 200 metres.

  • Come back to the bridge let’s take again the main path
  • Going upstream after a wide left bond it gains on Ponte dell’Isola ruins, traces of the numerous traffics between Tanaro and Arroscia river valleys by the Tanarello valley.
  • Further on landscape is wider and the route run nearly straight between the stream and some lines, still now used for hay yield.
  • Carrying on where terraces narrow, there are ruins of some frameworks (Case dell’Isola). From here it is possible to go uphill till the San Bernardo chapel.
  • The road pass on the Dova brook, then to south till another Tanarello affluent, the Piniella brook.
  • After a pair of turns, it gains on a intersection: a right hairpin bend goes to Casa Maddalena Soprana (1278 m.) but our course continue to the valley bottom.
  • Passed on another stream, the Maddalena brook, it gets to a plateau with a belt of red reafforested fir trees.
  • Now we are very next to our destination: after the Moneghe brook, another Tanarello affluent, and an intersection we must turn to the left side till the Tanarello bridge.

  • Passed on the bridge, it takes on the left side of the road where in the middle of an ample turn near a very small valley there is a short path going up to the right side, between wild roses and hazels.
  • Passing the hazel grove, then a coppice of beech trees whit some exemplars of oaks too, it goes uphill till a knoll above ruins. Now we are outside from the beechwood and the landscape too is wider. In front of us we can distinguish the Saccarello Massif.
  • It come back up along the crest till the Case Bausùn (1336 m.), under the Armasse Rocks.
  • Just above the houses (Case) a path goes on towards west where it finds some small brooks inside a pinewood (1500 m.).
