ItinerarySat Transit Hamburg AthensHamburg -> Athens (plane).
Athens Airport -> Nafplio (Bus)
Note: Several X busses depart from Athens airport. A bit confusing. Don't go to Syntagma, go to the Kiffisos (X93). In Kiffisos, Tickets are sold outside, not in the ticket hall.
https://www.visitnafplio.com/directions.html Sun Mykene, Argos, Nafplio
Morning: Bus to Fichti. Walk 3.5km to Mykene. Missed my return bus by 5min. Took a cab from Fichti to Argos and would recommend the same to you as the bus schedules don't really work.
Early Afternoon: Argos Agora and Amphitheatre (T).
Later Afternoon: Climbed Palamidi fortress (T) from the city. And also visited Akronauplía (T). Google isn't aware of the stairs, so it will propose a huge detour for Palamidi.
Mon Epidauros, Tiryns, MystrasMorning: Taxi to Epidauros. Was planning to take a bus back but it never showed. I got lucky as I founda free cab driver, but I would recommend negotiating a return rate with the driver from the start.
Lunch: Tiryns.
Afternoon: Bus back to Nafplio (run every 30-60min). Bus to Tripoli (once a day Mon to Fri). Bus to Sparti (not shown on any website or app, but there are frequent connections as all busses from Athens to Sparti will stop here). Cab to Mystras.
Tue Mystras, Sparti, Kalamata, Messene (T)Morning: Visit Mystras, then cab to Sparti and visit of Sparta akropolis (free)
Lunch to Afternoon: Bus to Tripoli (really slow) where I got lucky and got the connecting bus to Kalamata as it was delayed, too.
Afternoon: Cab to Messene (T) organized via hotel (60). Recommended.
Wed Kalamata, Pyrgos, Olympia, Pyrgos Beach
Morning: Bus to Pyrgos (8:30), then bus to Olympia. Museum in Olympia is a must visit.
Afternoon: Bus back to Pyrogs and walked to the beach. Nice and quiet.
Thu Pyrgos, Nea Figaleia, Bassae, Andritsana, Athens6 a.m.: Bus to the wrong Figaleia (Nea). Waited for 3h to catch the only available cab to Bassae and then drop of at Andritsana (50). During weekdays there is a direct bus connection to Megalopolis/Tripoli/Isthmus to Athens. Bassae is hardest WHS to visit in Greece by public transport. Only for the faithful or car drivers.
Note: Statement in review re Figaleia from Stanislaw is incorrect. There are two (old and new) Figaleias both 30km apart and the bus goes to the new one. Also, there is only one bus per week from Pyrgos to Andritsana. However, there are busses from Zaharo I think (different KTEL). Best option is to go to Andritsana and catch a connection there.
Fri: Daphni, DelphiMorning: Visit Daphni. Bus to Delphi. Note: Bus to Delphi runs from Liosion 300, not Kiffisos! Cost me 15 to correct that.
Lunch: Delphi. Entry is at the museum. Be sure to also visit the sites below the road. Museum is amazing (again).
Sat: Akropolis, Sounion, Lavrion (T)Morning: Visited the Akropolis and the Akropolis museum. They require two tickets. Stupid. Paid 40 in total for a combined Athens ticket (30) plus a museum ticket (10). Still, a great site and the museum, again, is a must visit. Most other components in the combined ticket can be seen from the outside, so not sure you need to get it.
Afternoon: Caught a bus to Sounion. Several stops in the city, so no need to go to the bus terminal. Google maps even has two stored (near Syntagma and the Akropolis). The Poseidon temple of Sounion is quite famous and part of the Lavrion (T) site. I hiked to the mining area where the primary component was closed. But mines dot the whole landscape so I think I am fine. I think this could make the cut as Mines in Antiquity OUV.
Afternoon: Return by bus to Athens. Note: Not all bus stops are marked. Essentially, these are near hotels etc. Wink to the driver.
Sun: Athens, HomeMorning: Did an early morning run of a few more sites included in the combined Akropolis ticket. Then airport, then home.
