Lake Chiusi, Natural lake in Val di Chiana, Tuscany, Italy
Lake Chiusi is a natural body of water in Val di Chiana, Tuscany, that stretches across several kilometers in a flat valley. It connects to Lake Montepulciano through a channel with a mechanized gate system that controls water flow between the two.
The area around the lake was an important settlement region during Etruscan times, when nearby Chiusi served as a major center of their civilization. Traces of this ancient culture remain visible in the landscape today.
The lake carries local stories tied to Saint Mustiola, shaping how people view and connect with this body of water. These tales remain part of how visitors experience the place today.
Walking and cycling paths run along the lake shores, offering routes through the surrounding landscape with views of historic structures along the way. These trails are best explored on foot or by bicycle, especially during dry weather when the ground is firm.
The lake is fed by multiple natural sources, with the Tresa as the main river, while a channel system manages outflow to maintain the water balance. This equilibrium between water entering and leaving has been crucial to keeping the lake stable across centuries.
