The Sienese Valdichiana is a stretch of open countryside, apparently remote but not far from the cities of Siena, Arezzo, Florence, even Perugia and Rome. It runs north to south, covering an area of about 691 km² in south-east Tuscany. On its northern border you can see the Apennine foothills and the surroundings of Arezzo; to the east lie the shores of the Umbrian Lake Trasimeno, almost touching Tuscany. At its southern edge, the high valleys of Lazio can be admired from the panoramic terraces of the southernmost villages of the Sienese Valdichiana, while to the west the sun sets every day on the hills of Val d'Orcia, a landscape declared a UNESCO World Heritage Site.
This central location in the Italian peninsula makes Valdichiana Senese easy to reach, not only from the nearby regions of Umbria and Lazio, but also from more distant areas, thanks to the A1 motorway connection, with the "Chiusi" exits to the south and "Bettolle" to the north. Then there is the Trenitalia Freccia Rossa high-speed train, which stops right at the Chiusi-Chianciano Terme station on its way betwen the major cities of Milan, Bologna, Florence, Rome and Naples.
