You'll enjoy Ovacik - its got a few bars but a short walk into Hisaronu and your spoilt for choice. Take a dolmus down to Olu and thats even better.
There's a Water Park in Ovacik, its as if your heading out of Ovacik opposite direction to Hisaronu. Its joined to a hotel, very small and a little run down, but the slides are fun. I think there is a bigger one in Fethiye - which you could try after sampling the fish restaurants there.
If you're adventureus try jumping of Babadag mountain strapped to a paraglider - fun watching them land on Olu Beach or for a little bit more money try the motorised ones that take off at night for a tour.
Take a dolmus/walk to the deserted village at Karakoy (ghost town) great photo opportunity or there's a few pancake cafes there to just sit and enjoy.
I'm sure you'll have a fantastic time there - we might be going back in 2012, it may be a toss up between
Icmeler and Ovacik.
Cheers John
