Alanya is cosmopolitan,plenty of night life ..good mix of Europeans and Turks...not as many Germans as people think..they mix Dutch and Danes and Germans up because the language is similar...and the english that are there are held in check because they are not visible.

Cirali is super as has been mentioned..i spent some days there recently at Canada Hotel..gorgeous.

For a really great holiday place you have to go to the stretch of the Med between Anamur and Mersin.

AND the best place out of the many along there is Kızkalesi...this is where many Turkish people have holiday homes, there is a super beach,some nice hotels big and small,low key night life,the best fish restaurants in Turkey..and the surrounding area is brimming with ancient Greek cities as well as sites that are famed in Greek Myths..such as the Caves of Heaven and Hell.
The castle of Kızkalesı (Maidens Castle) is set on a little island off shore ,the setting is spectacular.

To get there you have to fly to Ä°stanbul and then to Adana and then its about 90 minutes..so its a trek..but the effort is rewarded by the discoveries you make.
