A safe and pleasant place to visit with kids is the South-East Sicily.
Below you can find some quickly tips what you can visit:
1.Pantalica is a natural reserve located in the province of Syracuse. Pantalica is crossed by the river Anapo. Pantalica is also a necropolis of a thousand tombs that extend on the slopes and in the Anapo valley. To access the reserve there are two entrances one south and one in Nord. I advise you to get before that you arrive in a natural reserve a map of the area because not always you can find at the entrance. Inside this area there are no services therefore to go prepare something to eat and drink for children, hiking shoes and, if you want, a bikini for swimming in ponds inside the Pantalica. It will be useful to have a no baby buggy. I like to visit this place because there is no pollution. Your children can run without worries and you feel these relationship with nature. I also like to go there and to explore with my children the cavern full of bats. And I really advice you this place if you like in your vacation one day of quite, relax and fun with your family.
2. A very beautiful beach close to Syracuse is: Arenella. You can find the free beach and beach club. If you want visit Siracusa it is really close to the city and the water is clear like a crystal.
3.Another beach close to Siracusa is Fontane Bianche, here you can find as well free beach (not to big) and beach club. Some beach clubs have also a part with a pool and palm trees where you can have a rest with children from the hot heat.
4.Another extremely nice and clean beach, which is located inside the reserve Vendicari, is Eloro. Inside of this nature reserve there are not services, and therefore it is necessary to bring the beach umbrella, and something to eat and to drink. But I advise you to visit this beach, because the water and the enviroment is very suggestive.
5.Another amazing beach is San Lorenzo. There you can go to the free beach or in one of the many clubs Beaches. The sea it has nothing to envy to many seas postcard. In addition, the seaside resort is just a few km from Marzamemi a really nice village where you can have a dinner, have a drink, or watch many summer events (cinema under the stars, wine or fish festivals.)
6.Another nice beach, with always water clear like a crystal is Portopalo sea. This city is the the southest city of Italy. It is even more south of Tunis. There you can enjoy the seaside and you can eat excellent fish.
7.Another suggestive and beautiful beach and is the island of the currents. There there are a very clean free beach and beach clubs. The small island is close to the beaches and it is possible to reach the island of the current by swimming or just soaking with water up to your chest. For children it is unique experience because they imagine to be like an exploratory that visit the abandoned island.
8.Another very beautiful beach and close to Pozzallo is Santa maria del Focallo. The beach and is very windy (an advantage in summer days) and there you can do kite surfing.
9.Another beach that I would recommend is Vendicari, within the nature reserve where turtles lay their eggs. The advice I would give is to arrive early in the morning because to arrive to the beach you need to walk a little bit and if you go with the children it may be to hot. For this reason prepare water, food, beach umbrella.
