The Horti Leonini are a splendid Renaissance garden in the heart of San Quirico d’Orcia, created in the 16th century at the behest of Diomede Leoni. Characterized by perfect geometry and precisely manicured boxwood hedges, they represent a rare example of a public Italian garden. Divided between a flat formal section and a more natural area that climbs towards the woods, they offer a pleasant contrast between order and spontaneity. In the center is a statue of Cosimo III de’ Medici, while the paths invite quiet walks immersed in greenery. They are an ideal place for a relaxing break, amidst art, history, and landscape harmony.

La Balena Bianca is the most imposing limestone formation in the free thermal baths of Bagni San Filippo. It is a monumental waterfall of white limestone created by the deposit of thermal waters that spring up at 48°C a little further upstream. The place is truly fascinating, but there are also some negative aspects that, for fairness, I want to mention to avoid the surprise effect and to know what you are getting into: The first is certainly accessibility, the path to reach this natural wonder is decidedly muddy, there is no real path, if it has rained recently, you will find yourself having to walk in the mud. So if you want to come, I advise you to bring high waterproof boots to put on in case you find mud (very likely). The second sore point is the carelessness of people, the entire area is devoid of regulation and controls, left to the mercy of the crowd, so you can imagine the situation that arises on weekends or holidays. If you want to come and swim here, my advice is to come on a weekday early in the morning, or also late in the evening, not on weekends.

The Belverde Archaeological Natural Park, at the foot of Monte Cetona, is a place where nature and history intertwine in a suggestive way. Immersed in the woods, the park preserves a system of caves that were inhabited by humans since prehistoric times. Next to the Archaeological Park, the Archeodromo of Monte Cetona offers a faithful reconstruction of a prehistoric village, allowing for a direct understanding of the life of the ancient communities that inhabited these lands.

The Horti Leonini are a magnificent example of a classic Italian garden, laid out around 1580 by Diomede Leoni, after whom it is named. Leoni was a connoisseur of ancient and Renaissance art who, on behalf of the Medici, acquired works of art from Roman circles. Francesco I de' Medici himself gifted him a plot of land in the heart of San Quirico d'Orcia, where the Horti, which still retain their original appearance, would later be established. The gardens are divided into two sections: The lower, diamond-shaped area is enclosed by walls and clipped holm oaks and consists of triangular flowerbeds bordered by a double boxwood hedge. At its center is a sculpture attributed to the Sienese artist Bartolomeo Mazzuoli, depicting Cosimo III de' Medici (1688). In the other section stands the head of Janus Bifrons, a Roman-era sculpture that symbolically marks the boundary between the more natural and the formally designed parts of the garden. A travertine staircase leads to the upper plaza.
