The Pian dei Renai reservoir is located at 1170 metres above sea level in the municipality of Abbadia San Salvatore. It is not a natural spring but the result of an effective human intervention.

The first drilling to collect water from the subsoil began in the early 60s of the last century while the construction dates back to 1966. Its function is fundamental to bring water to Abbadia San Salvatore, Cantore, Vetta Amiata and Macinaie, but above all to guarantee the water resource to the vast area of Val di Chiana. The reservoir, nowadays kept in a well-preserved area, is immersed in a beautiful beech forest just above the chestnut trees elevation profile and near the “Sasso e Merchi” so named because of the border line with the former property of the Counts Cervini of Vivo d’Orcia carved in it, a place where some lines of behaviour are dictated within it. Among all the water reservoirs on Mount Amiata, Pian Dei Renai is among those located at a higher altitude.


The project “Le Vie dell’Acqua” is dedicated to the water resource and the rediscovery of the natural springs of Mount Amiata. On this ancient quiescent volcano the abundant presence of natural springs that gush out in considerable quantities constitute an immeasurable water reserve for a large part of the Region. From spring to spring, the paths identified and traced by professional environmental guides allow you to discover the vital importance of the Amiata waters and to be fascinated by their impetuous descent: from the springs at the top to the taps of the inhabitants of the provinces of Grosseto and Siena. In order to reach the gushing springs you have to cross medieval villages, centuries-old chestnut groves, silver fir woods and finally follow the traces that history and culture have carved in the past of this mountain. Le Vie dell’Acqua is a project that helps to discover the springs of Mount Amiata, promoting a slow and zero impact tourism. It is financed by AdF and Acea and supported by the municipalities of Arcidosso, Abbadia San Salvatore, Castel del Piano, Castiglione d’Orcia, Santa Fiora, Seggiano and Piancastagnaio.
