An extraordinary walk between the natural spectacles of the Sasso Pisano and Those of Monterotondo Marittimo. Walking through the medieval villages and its thermal springs, we will closely visit the sites of geothermal energy and the famous “Beer Vapors” brewery. 30 km starting from the center of the capital, Castelnuovo di Val di Cecina, up to the highest peak, “Aia dei Diavoli” (900 meters above sea level) with a view of the Cornate. We will then cross the “Biancane” area, a Unesco world heritage site for its uniqueness. An experience of pure fun, with adrenaline-fueled routes for mtb.
