About this site
Aspronisi is a small islet within the Santorini caldera, lying between Therasia and the main island of Thera, part of the volcanic rim formed by the Bronze Age eruption. The reef here is a beginner dive with a maximum depth of around 9 metres, shallower than much of the surrounding caldera basin, which otherwise drops away sharply. The seabed around Aspronisi is shaped by volcanic rock formations rather than coral reef, reflecting the area's geological origins.
