You step onto the sun-warmed path above the Aegean and the caldera unfurls: a crescent of drop-offs, whitewashed houses clinging to black volcanic rock, and the blue sea daring you to look down. The Fira–Oia rim trail runs roughly 11 km along the island’s volcanic edge, alternating paved steps, cobbles and dirt stretches while giving one uninterrupted stage of seascape and island peaks.
