Le Roste are striking reddish badlands located in the upper valley of the Merse river, near Boccheggiano (in the municipality of Montieri). Although they look like natural formations, they are actually artificial deposits of mining waste, sculpted over decades by the elements. These geological and landscape mounds have formed through very specific dynamics: Mining origin: The materials derive from the sorting and open-air roasting of chalcopyrite, a mineral extracted in the nearby Merse Mine. The red color: The characteristic vivid coloration is due to the high concentration of copper and iron sulfates. Erosion: In the decades following the closure of the plant (which occurred in the early twentieth century), rain and wind have eroded these mounds, creating pinnacles and gullies reminiscent of American canyons.

Chiusdino is an ancient medieval village located in the province of Siena, perched on the Colline Metallifere and overlooking the splendid Val di Merse. It is especially famous for its inseparable bond with the figure of San Galgano and for its proximity to the famous roofless abbey. The historic center preserves a timeless atmosphere, with stone houses and narrow alleys that wind along the slope. It is believed that Galgano Guidotti was born here around 1150. His supposed birthplace is one of the main destinations for those visiting the village.

Really beautiful loop tour, given the places it's hard not to be, but unfortunately we discovered that the track leads onto an impassable private property, please check where it stops to turn back! "Adventurous" alternative. Everything else magnificent! Staggia, Monteriggioni, the farms all very characteristic.

The perimeter walls are still partially visible, especially in the southern section, where an arched gate surmounted by three rounded stones stands. At the highest point of the hill stands the imposing stone keep, which extends around a courtyard. Within the walls is the church of Santa Maria Assunta, dating back to the 13th century but completely renovated in the late 19th century. It has a distinctive urban layout, dominated by an imposing stone keep arranged around a courtyard accessed through two round-arched gates, defended by a large tower with a massive base.

And after the effort, a lovely stop at the Barrino di Tatti. A snack just outside the medieval village, with views from the terrace and dining room spanning the Maremma all the way to the sea.
