Why It's Worth It

Santorini's rugged beauty is on display the minute you set eyes on the island, whether you arrive by air or by sea, on a cruise ship or a regular ferry. Its landscape carved from a volcanic eruption, it is one of the most beautiful islands not just in Greece but the whole Mediterranean. With high-end hotels and restaurants, a flourishing wine industry, beaches, and archaeological sites, it packs a lot into just 35 square miles. —Mike Gerrard
