I live close to the amazing 5 kilometre Konyaalti Beach in Antalya. Toward the city centre end of it there is a fantastic Beachpark with lots of beach bars, restaurants, shops and even a few nightclubs as well as a fairground and play areas for children.
It really is a great place and one you should definitely visit when you come to Antalya. Here is a video I made of it when I was there one day.
