5.Santorini, Greece
Encircling a sea-filled caldera, spectacular Santorini scores top points for its 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 color palette.
6. The Cook Islands
If you’ve ever dreamed of being a castaway in the South Pacific, the Cook Islands are for you. Strung between French Polynesia and Samoa but with strong ties to New Zealand, the archipelago’s 15 islands are among the most beautiful islands in the South Pacific.
