The ruins are quite large, but they do not cause much interest. I advise you to come in your car in the evening - at 6 o'clock. In the afternoon you will be like in the oven. The ruins are located on a hill, with a beautiful view from the hill. The pleasure is 100 liras per person, there are no discounts for children (at least for children 11 years old). The price for the content is clearly too high.
An interesting place! A wonderful view of the Dalyan Delta opens from the upper rows of the theater. And then you can walk down the streets of the ancient city to the very bank of the river. Beautiful nature, picturesque ruins. From there, Lycian Rock tombs can be reached in 5 minutes by car. It's really a majestic sight! To get a closer look at them, you have to go through the cemetery. You won't be able to climb into the tombs themselves, but that's not what they were built for. That's exactly how the architects intended them: majestic and unattainable.
In my opinion, it is just good to go here with organized excursions. I'm not a big fan of this approach myself, but there are a number of advantages specifically here. Firstly, the tour is more for recreation, you don't need to go anywhere, they carry you everywhere. For example, we had very busy days before in terms of walking, so it's just relaxing here. Secondly, the tour itself turns out to be intense. They brought them, put them on a boat, sailed, showed the tombs, took pictures, ordered blue crabs, ate blue crabs, fished blue crabs, swam on the beach where turtles breed, fed the turtles with the remains of blue crabs that they had eaten before. Turtles are cool, by the way. We returned back, had lunch (you can't get enough of blue crabs). And in the end they are brought to some kind of mud baths with healing clay. I don't know what she treats there, but at least it's fun.
