Thirasia (Therasia) Tours and Activities

star-4.5
1,186 Reviews

Before a violent volcanic eruption in 1650 BC, Thirassia was part of Santorini’s mainland and now the pretty islet lies just off its western coast. With small pretty beaches, blue-domed churches, ancient stone villages and a population of only about 200, the little island is a perfectly serene spot to visit.
