     September can be a depressing month. The summer holidays are over, it's time to go back to work or

school and Christmas is four months away. However, for some people it's the perfect time to get away.

     These days more and more people are taking their holidays late in the year and for good reasons.

Holidays in autumn can be cheaper, the resorts are less crowded and the weather isn't as extreme as it is

in the summer. So, where are the best places to go? Here are our top tips.

     Sardinia (in Italy) has an average temperature of 27℃ in September. It also has "Autunno in Barbagia" (Autumn in Barbagia) a series of festivals that take place in 27 villages in Barbagia, a mountainous

region of inland Sardinia. The festivals continue from September to December, so there's always something happening. There are street markets, craft workshops and there's lots of eating and drinking (This is Italy,

after all).

     Dubrovnik Croatia has become very popular in summer but it's quieter and more pleasant once the

crowds have left. The weather is still warm but less humid. You can take a ferry to the popular beaches

on the islands of Sunj and enjoy it with locals.

     Dahab Egypt, is extremely hot in the summer with temperatures up to 38℃. However, the autumn is

cooler while the sea is still warm. This makes Dahab the perfect place for snorkeling and windsurfing.

There are also interesting historical sites to visit such as the Coloured Canyon, with its dramatic rock

formations, and St Catherine's Monastery, at the foot of Mount Sinai.

     Kas is a relaxed fishing village on the Lycian coast in southern Turkey. There are plenty of things to do and the temperature has dropped (so you can actually enjoy doing them!) Kas is a good place to stay if

you want to walk part of the Lycian way: a long-distance footpath that stretches for 500km from Fethiye

to  Antalya through the ancient land of Lycia. There are also watersports, of course. The best time to go

diving is supposed to be after the first rains of autumn (usually between late September and early October) when the fish become most active.

     Marrakech Morocco is another good destination. The city itself is a fascinating place to spend a few

days. When you have had enough of that, go to Tigmi, a beautiful hill town about 20 kilometers away.

There's a hammam (a Turkish bath) and a large heated pool, which makes it the perfect place to relax.

     Wherever you go this autumn - have fun!
