One of the most requested excursions on the island of Sicily is a visit to the Alcantara Gorges, formed after an eruption of a small volcano north of Etna. The lava flow slid into the sea forming the Schisò. Over time, the river eroded basalt forming high walls and creating an authentic barrel with black-walled gorges, light reflectance gives it an almost magical charm. The name of the river (Alcantara) is of Arabic origin and refers to a Roman bridge built for flood prevention. You may travel long the channel of the gorges in some areas if you have the appropriate equipment (shoes especially).
