We'll be on short vacation in Greece August 24th - September 5th. First 2 nights I booked in Athens, then we are moving to Skopelos by bus-ferry, and spend 8 nights there till August 3rd. For now I left the last night and day (we have a night flight between September 4th and 5th) not booked yet. I figured out that on the way back there is only afternoon ferry to Ag. Konstantinos (3-4 p.m.). We need your advice friends, what is the best way to spend the last night and long day of Sept 4: making a stop in Skiathos, and returning to Athens next afternoon right before flight... or not to risk with weather/sea conditions and go straight to Athens after Skopelos and spend the last day around the city (Attica?), or on the way from Sporades somewhere between Ag. Konst. and Athens? Any ideas about a nice and interesting place reachable by public transportation in that area? We will be visiting Greece for the first time. Thank you in advance.
