The beach definitely needs to be made more attractive to tourists, people do not want to lie, sunbath and swim amongst dog mess, litter and cigarette ends and that’s if you can even get there before being attacked by a street dog or run over by an e-bike, Madge mobile, scooter or lycra clad cyclist.
The beach is run and maintained by Fethiye belediyi who charge for the use of sun loungers... perhaps if the bar/restaurant owners were allocated and charged for a section in front of their business it would possibly improve the situation but hey that’s a whole new issue.
Current prices in Turkey in general are making a lot of visitors think twice about where they holiday this year so it is definitely something that needs addressing sooner rather than later.
There has been clean up campaigns in the past but not recently as far as I am aware.
