A suggestive place that can be easily reached on foot. The smell of sulfur is more intense only near the source, but it does not pervade the surroundings.

From here, the view sweeps down over the spectacular Balze del Valdarno, spires of clay and sand sculpted by time after an ancient prehistoric lake dried up. Their striking shapes create a unique landscape, contrasting with the surrounding vineyards and green hills. A panorama so evocative that it inspired Leonardo da Vinci, who depicted these forms in the background of works such as the Mona Lisa and the Madonna of the Yarnwinder.

Piantravigne is a small medieval village overlooking the spectacular Balze del Valdarno, clay gullies created by the retreat of an ancient lake. The landscape here is striking, almost lunar, and makes this place truly unique. A Pazzi castle once stood here, destroyed in 1302 after a siege during the battles between the Whites and the Blacks. This episode is also recalled by Dante in the Inferno (Canto XXXII).

Path impassable! We dared to make a path ourselves, whereby one of us was badly injured.

Borghetto overlooking the Balze del Valdarno. If you climb from the valley, a 1km climb with good gradients. I did it downhill from Setteponti.

The tour led to a very narrow, overgrown, thorny path just before the rocks. So it's better to look for another path in that section! Otherwise you'll end up on a farmer's private property and walk across his field. There's already a sign there saying you shouldn't go there. The route should be changed!

In some parts the path is difficult to pass (narrow, slippery, high vegetation) and you walk partly over private land of a farmer, with large barking dogs (fortunately they kept their distance this time, but still not very pleasant to walk). It is better to continue to follow the main path, which also has an official walking route (red and white striped). Otherwise a very nice walk!
