Monterotondo's surroundings are as breathtaking as the town itself. They are full of magical hidden corners, like the beautiful thirteenth-century Romanesque church of Santa Croce, or the castle of Cugnano, built around mines.
The Bagni del Re Porsenna, an important eighth-century series of hot springs, are worth a visit, as is the sanctuary of the Madonna del Frassine. But it is the enveloping landscape that makes Monterotono Marittimo truly unique and truly able to enchant the visitor with its unmistakeable charm.
If you want to make a real day of it, visit the Biancane nature park, which lies just outside the town walls. With a guided tour, you can trace the history of the geothermic activity here.
In the lower part of the park you will find the Chiorba spring, where the water, having come from deep underground, surges to the surface at an extremely high temperature. Continuing on the path, you get to the upper part of the route: the Biancane. The earth throbs with heat, the air is heavy with sulphur; columns of steam dissolve into the atmosphere, and the gaze lingerss over the strange colouration of the rocks and plantlife.
The walk will keep amazing you with the bizarre phenomena along the way: the fumaroles, the geysers, the mofettas, the sulphuric smell and the jets of steam.
You will appreciate the area even more on the special 5-day trail, which really plunges you into the Metalliferous hills and untouched nature that they offer.
