A particular tour of the Sicilian hinterland, to discover little-known historical and monumental sites, outside the usual tourist circuits. We will visit the Petra Calathansuderj, the Comitini sulfur mines of the large mining park, the medieval tower of Salto d'Angiò, the ancient and fascinating stone village of Passo Funnuto with the last Maccaluba (volcanello, Geyser) that can be visited up close.
