Impress even the most excursion-weary of kids with a trip to Mount Etna, which is Europe's largest active volcano. You can ride over the mounds of smoking lava by cable-car or opt for a 4X4 adventure through the moon-like volcanic landscape.
Hit the capital. Nowhere is Sicily's past more evident than Palermo, where you can explore Greek, Roman and medieval influences and get the kids spotting monsters peeking out from the Baroque architecture. With older kids, or those with gory imaginations, visit the Convento dei Cappuccini's catacombs to see the mummified remains of Palermo's 16th- and 17th-century noble classes.
Delve into Sicily's long tradition of puppet theatre. There are at least five puppet theatres in Palermo and some in other major towns, including Syracuse (La Dei Pupari) and Acireale (Teatro Pupi Macri). Plays are usually in Italian, but the lively battles and music help little ones follow along. In Palermo, combine a puppet show with a trip to the Museo Internazionale delle Marionette Antonio Pasqualino, dedicated to Sicilian puppetry.
Pay a visit to the Museo del Giocattolo Pietro Piraino in Bagheria, with more than 700 toys from the last four centuries.
Let the kids run off some steam at Bioparco di Sicilia, a zoo, playground and dinosaur park in Villagrazia di Carini close to the capital.
West of Palermo, browse the morning fishmarket in Trapani or visit the saltpans between Trapani and Marsala, with enormous piles of salt drying in the sun and a small Museo del Sale inside a restored windmill. Also nearby is the vast archaeological park of Selinunte, where kids can have hours of fun exploring Greek ruins.
East of Palermo, near the Madonie National Park, take advantage of the ropeladders and zipwires on offer at Parco Avventura Madonie, where you can also stay the night in treehouse, tents in the trees, tents on the ground, or B&B rooms. The National Park is also a great place for mountain-biking, trekking and horse-riding for all ages.
Although many of the island's beaches are pebbly, seek out some good snorkelling in Sicily's clear waters. For more watery fun, hit the waterslides at Etnaland aquapark, themepark and prehistory park on the east coast (themepark breaks at nearby hotels are available).
Stay in one of the island's east coast resorts, but after lazing by the pool, dress up and head out for to join in the communal evening stroll or passegiata. At the popular resort of Taormina, enjoy the cable-car from the beach at Mazzaro, which takes you up to the town to explore the famous Greco-Roman amphitheatre.
In the rest of the Sicily, visit the temples at Agrigento and Segesta or the Roman-era mosaics of Piazza Armerina, perhaps breaking up the journey with an afternoon at the Parco Acquatico Conte, a water themepark.
If you have more time, take a trip to one of the smaller islands that Sicily controls offshore, including Ustica and the Aeolians (mainly Stromboli, Vulcano, and Lipari), where you can enjoy a family mud bath.
