It's the trail n° 47, belonging to the CAI "Valdarno superiore" section, a nice ring walk inside the Tuscan hills (Arezzo), among vineyards, olive grooves, medieval villages and castles.

We start walking at the San Martino village, very close to the first sign on the trail. It's a ring walk, we could go in both direction: we decide to go left, towards Montebenichi village. The path is on a comfortable dirt road, in the background there are the snowy Appennini mounts. Thera are so many indication on the path that is not possible to get lost.

We already look at Montebenichi, our next step inside a typical Tuscan panorama, among vineyards, olive grooves, farmhouses and cypresses; we also cross a few almost dry torrent. On the path there is the small Saint Francesco church, perfectly set in the panorama; after 7km, (400 meters height difference), we reach Montebenichi village, where we decide to stay for lunch. It's a very nice village, totally built with stones, there also are a hotel and a restaurant if you are looking for a longer break.

We restart after lunch, after 6 km walking in the Tuscan countryside we get the small Cennina graveyard. The village seems similar to Montebenichi, but indeed is unkempt and with no services for tourists. We leave Cennina to go inside the only uneven section on the trail, then we pass close to an old mill now used as holiday house and also close to a nice vineyard just before we reach Duddena, a nice village suitable for a break before the last section of the trail that will bring us back to San Martino village.

We walked for about 20 km, rising for 800 meters. We broke the path in two sections, San Martino-Montebenichi (7km) and Montebenichi-San Martino (12 km); probably it would be better to leave from Duddena and have a break for lunch at Montebenichi or viceversa, so that you can divide the path in two almost equal sections and also have a break in a village that can offer to you some places to stay in (restaurants, bar...)
