About this site
Thirasia is the smaller, less developed island across the caldera from Santorini's main town, and its shoreline drops steeply into the same volcanic waters that fill the caldera basin. Dive sites along this coast are typically reached by boat from Santorini or from the small settlements on Thirasia itself.
