Port of Ia and around the Caldera

Santorini caldera is a large, mostly submerged caldera. The caldera measures about 12 by 7 km (7.5 by 4.3 mi), with 300 m (980 ft) high steep cliffs on three sides. The extraordinary beauty of Santorini's high walls, draped by whitewashed villages, combined with a sunny climate and perfect observation conditions, have made it a magnet for volcanologists, as well as a highlight of tourism in the Aegean.
