Deep in Sicily's interior, the fortress city of Enna (altitude 2,844 feet) commands exceptional views of the surrounding rolling plains, and, in the distance, Mt. Etna. It's the highest provincial capital in Italy and, thanks to its central location, is nicknamed the "Navel of Sicily." Virtually unknown by tourists and relatively untouched by industrialization, this sleepy town charms and prospers in a distinctly old-fashioned, Sicilian way. Enna makes a good stopover for the night or just for lunch, as it's right along the autostrada between Palermo and Catania (and thus Siracusa).
