The best way to see all those interesting sites is to plan a well-organized roadtrip with a camper or caravan. In this way you will have the flexibility to travel whenever you prefer, as there is no hotel waiting for you. In most of the greek camp sites you can choose your own spot even if you have a late arrival and check-in the next morning. The highways in the Peloponnese are all recently built, which makes driving a lot easier. In the villages the roads are narrower but you can still reach them with a camper.
In the Peloponnese you can find many beautiful campsites of high quality and excellent services.
If you don’t own a camper van you can always rent one in Athens and start your dream holidays as soon as possible.
