I am trying to decide what the nicest day trip by car would be from Herakalion. I am interested in covering a lot of ground and seeing as much as possible. One thing in particular that I wish to see is the Libyan sea on the south coast and the mountains. If I leave Herakalion early and need to be back for a 19:30 flight to Santorini what would my options be? Would it be doable time wise to drive to Hora Sfakion and then drive from there to Preveli beach before coming back to Herakalion? Is that even a nice drive through the mountains etc or can I do better?
