Arrival point: Historic center of Monterotondo Marittimo (about 530-539 meters above sea level). Total elevation gain: Approximately 450 meters distributed along the overall ascent. The Two Main Variants The classic route (SR 398): Follows the main road. The total route from the plain of Suvereto The "Wall" of Frassine (SP 136): Turning right onto the Strada Provinciale 136 "Frassine", you face the hardest and "most brutal" variant.

A medieval village in the northern Maremma, between ancient ruins, geysers and boraciferous fumaroles Lost in the Colline Metallifere, hidden among chestnut woods, stands the medieval village of Monterotondo Marittimo, which owes its name, Mons Ritundus, to the conical shape of the hill on which it stands. The territory of this municipality marks the intersection of three different provinces: Pisa, Livorno, and Grosseto. Surrounded by Mediterranean scrub, which extends towards the sea, it is a perfect destination for all lovers of clean air and natural beauty. The origin of the village is certainly medieval, demonstrated both by the characteristics of the narrow streets and by the conformation of the inhabited area, in fact the houses are built close together and the outermost dwellings were built on the defensive walls. In the territory there are also springs of bicarbonate-calcium water that gush out at 43°, used until a few years ago for thermal purposes at the Terme del Bagnolo.
