Maybe you could take a little trip to Kayakoy the ghost town from Oludeniz. That is a lovely day out and we like to find somewhere traditional that has tree houses and have a ready barbeque bought to us and we cook our own selection of meats, tomato, pepper and onions to eat with our mezes.
There is a nice breeze in Kaya so walking around the ruins before lunching can be quite pleasant.
You may need to change Dolmus at Hisaronu so worth checking with the drivers in Olu what time the Kaya Dolmus gets to Hisaronu and also the check the last one back from Kaya as they didn't use to run so late.
Some people like to walk to Kaya but it is a hot and long climb up from Oludeniz; not so bad coming back down.
