If you want to get to the lake from Dalaman, it is better to drive via Kayadibi and Kızılkaya. There is asphalt. Then stay on the left bank of the lake, the path on the right leads to a peninsula (!).
Also, the paths to Dalaman from the lake are not (!) asphalt like in Komoot, but about 17 km of dusty roads, but 11 km of them allow you to shoot at a speed of 40 km ;)
