By the looks of it, it could be off of Mendos Cad. Behind the Shell petrol station. Although the address isn't very helpful, I think one of the pictures shows the 2 mobile phone towers at the top of the hill from Fethiye.
Oludeniz IS 15 minutes away, but by car. You definitely wouldn't want to walk it. You have to be going at a very brisk pace to do Hisaronu in 10 minutes too.
