Hotels in Santorini Caldera, Greece

Santorini Caldera is a volcanic caldera in the Aegean Sea, famous for its dramatic cliffs and sunsets viewed from Oia. Summers are hot and dry (80-90°F / 27-32°C), perfect for sailing across the caldera's deep blue waters, while milder springs and falls (60-70°F / 15-21°C) are ideal for hiking the 6-mile trail from Fira to Oia along the caldera edge. During the sunny dry season from May to October, you can explore the ancient ruins of Akrotiri, a Minoan settlement preserved by volcanic ash, or hop between the caldera's islets like Nea Kameni to see active volcanic craters.
