We got there by car, the road is great. There is a parking lot, a small cafe, a toilet, souvenir shops. The territory of the ancient city of Tlos is large, you can climb up to the tombs themselves. Fethiye tombs are high in the rocks, you can only see from below. It is also convenient to drive up.
An interesting historical place. Good views of the city and the bay. There's not much to see, but what's left of the tombs is impressive. You can visit, but preferably with a guide. If you go or go on your own, then you need to read about the place.
If you look from the road, it's beautiful, interesting, and historical, but I wouldn't pay money for admission. Approximately the same views as from the tombs can be seen by walking a little further down the road.
