I'm travelling to Athens and would like to see Delphi and Meteora. I'll be leaving Athens in the morning on the 13th of June 2018 to hopefully arrive at my hotel in Kalabaka on the same day. I'd like to go from Athens to Delphi and spend some time there, then go from Delphi to Kalabaka. Otherwise, the other option is to go straight to Kalabaka from Athens, then on my way back to Athens on the 15th of June 2018, drop by Delphi on the way to visit.
Does anyone have any suggestions how to make this trip without a car? I’m hoping that there are convenient public transits such as bus or train that can help me do this trip. I read some sources that there was a bus, but I couldn’t find the bus name/number, where to take it, nor its schedule. Also, on my way back from Kalabaka directly to Athens, if anyone could give me tips on how to make this trip as convenient as possible, I’d greatly appreciate it.
