This gate is another of the attractions of the ancient city of Perga. I recommend definitely going to the ruins. These are some of the cheapest and most convenient ruins. You can get to the city yourself by bus (get directions via Yandex maps at your hotel). You need to go in the morning to get around all the facilities all day long, and there are a lot of them on the territory. Moreover, the entrance ticket includes the cost of visiting all facilities (for example, the amphitheater in Side, the baths are separate).
When you are in the ruins, be careful and keep an eye on the children.👍
