More ways to explore the area's outdoor wonders
The road south of Athens narrows into a ribbon of sea and stone; olive-dusted hills fall away to reveal the squat Doric profile of the Temple of Poseidon, perched where wind and waves have rubbed the cliff face smooth. You arrive with the Aegean laid out like a moving mirror, columns casting long, honest shadows.
