You can reach the ancient city many different ways: on foot, on horseback, or by carriage. I recommend that you go on foot, although the entrance ticket includes admission for a horse. If you go on foot, you can take pictures on the way and you will see nice touches of color. With the heat, it is rather tiring, but it´s worth it. Coming back tired, it is a good idea to use one of the other modes of transport previously mentioned.
