Stepping out of Fira’s white alleys, the caldera trail immediately opens into a parade of cliffs and sea—wind shaping the pumice cliffs, the Aegean daring you toward Oia. The trail threads past Firostefani and Imerovigli, drops to quiet chapels and volcanic outcrops, then climbs again toward the famous blue-domed rooftops of Oia.

Santorini’s caldera formed after a massive volcanic eruption in the second millennium BCE; the island’s villages grew on the rim of that collapsed volcano and reflect centuries of maritime and agricultural life.
