2. Santorini, Greece 18°C ()64.4
Encircling a sea-filled caldera, spectacular Santorini scores top
points for dramatic beauty. Bleached white villas tumble down
volcanic cliffs. Blue-domed churches rise against the sparkling sea,
and bright sprays of bougainvillea add to the eye-popping canvas of
color. Perched atop the black lava cliffs, the settlements
of Firá and Oia are the island's most picturesque and pricey,
destinations, and Oia ranks among the most photographed
locations in the world. Other highlights of the island
include Akrotíri Archaeological Site, Ancient Thira, the black sand
beach of Perissa, and of course, the sublime sunsets. Sailing into
this stunning caldera surrounded by soaring sea cliffs makes an
unforgettable first impression.
