Greetings!

My friend and I will be staying in Polichrono in July and we would like to visit Dion and Stageira. The only travelling option for us is by bus, because we are not rich enough to hire a taxi.

I understand that first we will have to go to Halkidiki KTEL bus station, but how to proceed from there???
Should we go to Makedonia Ktel? Or is it possible to catch the bus at Halkidiki Ktel?
And could you, please, tell me if there is a site where I can look up the timetables.

Please, help. Thank you in advance.
