3Santorini

The Santorini Caldera is a collection of islands formed by the exposed rim around the sunken crater of an active volcano. These islands contain unique archaeological, architectural, and geological features that make Thira (the largest island) one of the most popular Greek islands for sightseeing. 

You’ll love the picturesque, whitewashed houses and blue-domed churches. From the capital of Fira, you can admire breathtaking views across the caldera. If you’re feeling adventurous, take a boat trip to the uninhabited islands of Palia Kame and Nea Kameni in the center of the caldera. There you can witness volcanic gas emissions and swim in the hot springs heated by the volcano.
