I am beginning to plan a trip to the Peloponnese for April or May of 2027. We do not need to visit all of the possible ancient sites, and the exact number of days is not critical. We will have a rental car.
After reading lots of forum posts about the Peloponnese, I know it is hard to choose! We want to visit some "must-see" sites plus a few less visited locations, and still have plenty of downtime to sit in a plaza.
Arrive in Athens (may stay overnight depending on arrival time from the US)
Nafplio 5 days
Kosmas 1 night (drive coastal road via Leonidio)
Mystras 1 night
Limeni 2 nights (explore Mani Peninsula)
Koroni 2 nights *or possibly choose between Limeni and Koroni areas, staying longer in just one location
Stemnitsa 3 nights
Depart Athens
Thank you for your feedback and suggestions for this itinerary draft!
