About Santorini
Santorini is a volcanic island in the Cyclades, in the central Aegean, recognisable by its steep caldera and the white villages that hang above it. The island was formed by a great volcanic eruption, so it has no classic sandy beaches but rocky, volcanic-coloured shores. Santorini is a destination for views, sunsets and quiet couples more than for a family beach holiday. For Macedonian visitors it is reached by flight, most often on package trips. Summers are hot and dry, with August sea temperatures of around 26°, and the season runs from May into October.
What to See in Santorini
- The caldera and the village of Oia with its famous sunsets
- The main town of Fira above the sea
- The red and black volcanic beaches
- Ancient Akrotiri
