There is the town of Belek, not very interesting (IMO), with some shops and just a couple of bars, and restaurants. OK for a visit one afternoon if you have nothing else to do. Depending on which hotel you stay in, it may be some distance away.! In high season there is a little tractor train that stops outside the hotels, to take you there, other than that, you may need to get a taxi. There is also another town called Kadirye (spelling?) that I have heard is better. I haven't been, so can't comment. Have you looked on the resort reviews on here? Some interesting comments!
