Overall: Great place to stay along the east coast of Sicily. You need a rental car (the public bus experiment to Catania did not work out), but as soon as you get used to the Italien traffic style you will have lots fun getting anywhere you like.
Totally recommended: The panoramic drives Etna south and especially north! Further: A hike along the Etna (of course), the Alcantara river, Castelmola (/Taormina), Siracusa and a hike in the Vendicari nature reserve at the south-eastern coast.
