Our journey proceeds to the border between the provinces of Siena and Grosseto, up through the Cornate di Gerfalco, where nature reveals herself in all her beauty. Reaching a height of 1,060 metres, this calcareous range dominates a large part of central Tuscany, and from it we can see Siena and Monte Amiata. On the opposite side, in the Tyrrhenian seascape, a clear day will make it easy to pick out the islands of the Archipelago and even Corsica. Situated in the centre of the Cornate and Fusini Nature Reserve, this mountainous highland is genuine environmental paradise, where little shrubs, meadows, forests of turkey oak, holly oak and chestnut trees vie with the rocky slopes, partially covering them.
Our starting point is Gerfalco, the ancient mining village on the mountainside. Close to the Colonia Montana Santa Maria, a clear signpost points us on to a rocky road along the ridge that faces south-east. From here we start a gentle climb for around three kilometres, noticing the holly oak woods and the flora typical of the Cornate, before arriving not far from the summit. We pass through coniferous woods to reach one of the highest points, where we will meet one of the first cairns, curious piles of stones piled up without cement, amply distributed over the Cornate. From here we begin our rapid descent down the western slope to arrive, after little more than a kilometre, at the mine of red ammonite, the red marble used to embellish the Duomo of Siena. We continue the descent down the path, which from here becomes easier, and ignore the crossroads with path no.11, called Viottolo dei Selciani. Having arrived at Campo delle Rose, near an old mine of heaped limestone called Cava di Romano, we walk level for a bit along the white gravel road, which will take us within a stone's throw of the elegant Avveduta Chapel. We go past the building for about 300 metres and then take a little road on the left that will again bring us onto the path that we were on before reaching the village. Arriving at a crossroads, we turn right and proceed along the lane to return to our starting point.
