About this site
Thirasia Reef II lies off the small island of Thirasia, across the caldera from Santorini proper in the Aegean Sea. The islet's coastline is largely volcanic rock, shaped by the same eruption history that formed the Santorini caldera, and dive sites here are typically reached by boat from Santorini's harbours.
