What is Castelnuovo di Val di Cecina known for?

Natural steam vents around Sasso Pisano, hissing through the stone streets and staining them yellow with sulfur. Medieval and modern copper extraction under the Republic of Pisa, active in the surrounding hills into the twentieth century. Apennine subsistence crop still harvested on the slopes above town, with autumn sagre across the comune.

When is the best time to visit Castelnuovo di Val di Cecina?

Apr–Oct. April through June is dry and green at altitude, with the fumarole steam visible against cold morning air. September and October are the chestnut season, with the smaller sagre across the comune. July and August are warm but tempered by elevation; the soffioni feel less dramatic when the air outside them is already hot. November through March is quiet. The hills cool, the steam plumes show against the cold sky, and the natural thermal pool at Sasso Pisano sees the few winter bathers who know it. The Rocca Sillana under low cloud, with the steam rising from the next valley, is the picture of this corner of Tuscany.

Why come

Castelnuovo di Val di Cecina sits at 576 meters on a high spur above the Cecina river, in the geothermal heart of Tuscany. The hills around the town are scored with fumaroles and boiling pools, the soffioni that Francesco Larderel learned to harness in 1818 a few kilometers down the road. Sasso Pisano, a frazione of the comune, has natural steam vents in its streets and the Parco delle Fumarole, where the ground hisses in winter and stains the stone yellow with sulfur.

The medieval village was a copper-mining center under the Republic of Pisa and the Aldobrandeschi, and the surviving towers of the centro storico mark the boundary of the old ore concession. The Rocca Sillana, a Pisan-Florentine fortress at 528 meters on the next ridge over, surveys the entire upper Cecina valley. The chestnut, a crop that defined Apennine subsistence, is still harvested on the surrounding slopes each October.
