To discover the Back Door Peloponnese, head to its remotest frontier. The Mani Peninsula is the southernmost tip of mainland Greece (and of the entire European continent, east of Spain) — and it feels like the end of the road. In the Mani, travelers discover a timeless region of rustic villages and untrampled beaches. A day's drive around this desolate, rural peninsula offers dramatic mountain scenery and bloody history all tied up in an evocative package — making hedonism on the Mani coast feel all the more hedonistic. At the end of the day, you can retire to charming Kardamyli.
