If you know where the Tues Market entrance, from the main road is, then cross over at traffic lights and you will see two petrol stations (where the one way system out of Fethiye becomes two way).
Behind the petrol stations is the Dolmus Bus Station and just look for the Uzumlu sign. I haven't got the time table but I'm sure someone else can help. If not the time table is up in the Dolmus Station.
