Mandarin Oriental, Costa Navarino

Ninety-nine villas and suites tucked into a Peloponnese hillside above the Bay of Navarino, all curved modernist lines, terrazzo, rattan, and hillside botanicals that smell like a Greek myth. Mandarin Oriental's first Greek property holds a Forbes Five Star, and the property earns the hush: private plunge pools, yacht charters, cave rappelling, and a handful of exclusive restaurants mean very little reason to leave, which is presumably the point.
