Hotels in Santorini Caldera, Greece

Santorini's Caldera is a volcanic crescent in the Aegean Sea, famous for its cliff-top villages with white-washed buildings and blue domes. The climate is Mediterranean with hot, dry summers reaching 90°F (32°C), perfect for watching the sunset from Oia's Byzantine Castle ruins, and mild winters around 55°F (13°C) when you can hike the caldera rim from Fira to Oia or tour the ancient ruins of Akrotiri. For a quieter vibe, stay in Imerovigli and kayak in the caldera's warm summer waters, or visit the volcanic hot springs at Palea Kameni during the sunny spring.
