Squali (sharks) come out at night when there's no moon. Linea Blu's divers go to film this special event off the coast of Sicily.

Linea Blu takes us to the magnificent town of Taormina, with its centuries of history and natural beauty.

There's a beautiful tiny island near Taormina, with its ancient castle, and some unique fauna.

From the deep blue sea to the high, volcanic Mount Etna, there is still much to discover in Sicily.

Near Mount Etna is the river Alcantara, with its unique bed and walls that create a marvelous natural landscape. It's also a choice spot for extreme sports like hydrospeed, kayaking and rafting.

Acireale and Aci Trezza are two small towns in Sicily that get their names from Greek mythology, and they in fact look out on the Islands of the Cyclops, so this area, besides being incredibly beautiful, also has an important and very ancient place in history and myth.

More about Aci Trezza and the Cyclops sea stacks, and their roles in legend and tradition.

By way of Aci Castello, another town dedicated to the mythological Acis, we finally reach Catania, the second largest city in Sicily.

You won't want to miss the authentic and lively fish market in Catania, nor Brucoli, a fishing village nearby, with its grottoes and castle.

Augusta is a port city on the eastern coast of Sicily. There are two ancient fortresses and a tower built to defend it in the sixteenth century, and later on, it became a base for dirigibles and seaplanes during World War II.

Augusta is famous for the castle where Frederick II had his court in the thirteenth century. Every year in September, there is a medieval festival recreating the court, with authentic food, costumes and dancing.

Visit beautiful Syracuse and the island of Ortygia, the ancient part of the city, with its unique panoramas and rich history of Greek theater.

This fascinating segment is about rivers, aqueducts, caves, and perhaps the dwellings of the earliest prehistoric man.

The final segment of this overview of Sicily, is an underwater journey near the coast, where the water is a deep blue, and where there are many interesting species of marine animals.
