Santorini

Around 1650 B.C., a major volcanic explosion caused the core of what was previously a single island to collapse and sink into the sea. Some believe that this was the initial location of the long-lost city of Atlantis, which vanished into the depths of the ocean. Beautiful beaches and magnificent whitewashed mansions still protect what remains of this fabled metropolis. Santorini is now made up of two inhabited islands and various islets. The majority of visitors spend their time on Thira (the biggest island in the archipelago), which is home to Santorini's major cities, including Fira and Oia. Sleepy Thirassia is also a nice place to go for a quiet day trip. Also, don't dismiss the calmer islands: Nea Kameni and Palea Kameni are worth seeing.

The first thing you should do in Santorini explores the multicolored beaches - the black and crimson sands make for an unforgettable visit. Next, explore the archaeological marvels of Ancient Akrotiri, which has been wonderfully maintained, or climb to Ancient Thera to witness the remnants of three civilizations, including the Romans. From there, you may get a stunning view of the caldera, a bright turquoise body of water that acts as the center for the archipelago's many isles. Some claim you just need a day to experience the attractions of these islands (they are a popular port of call for cruise ships), but you'll need a few days to a week to properly soak in everything Santorini has to offer.
