You go through the forest from opposite Ovacik cemetery.
Keep following the path, on and on and on, just don't leave that small road. Some of it is very hard going, uphill round bends and feels never ending, so you would need to be quite fit to cope with it.
Just as you feel you can't take anymore it levels out and goes downhill.
You will then meet the Kaya to Fethiye road, there's a very small cemetery on the corner.
We then took a small rocky road to the right, it's the original Kaya road that they used to take the donkeys up, which goes round a few bends but ultimately meets the main road again shortly before the first signs of civilisation, Kale Park, some traditional houses and then down to the sarcophagus and onto the Fethiye back road.
you could just stay on that main Kaya to Fethiye road after the tiny cemetery rather than do the rocky track, it leads to the same road anyway.
