Classically known as Thira or Thera, this island is located in the southern part of the Aegean Sea and is part of the Cyclades islands. It's actually the southernmost member of the Cyclades and is home to around 15,000 people, covering an area of around 28 square miles in total. One of the biggest ever volcanic eruptions was witnessed at Santorini several thousand years ago, with this big event having an effect on the surrounding landscape and allegedly influencing various Greek myths and legends of the time.

It's an island with a rich history and several major settlements including Fira, Oia, Kamari, and Emporio. Tourism is the main contributor to the economy of this Greek island, with lots of people visiting Santorini, especially in the summer, to bask on its beaches, explore its historic sites, enjoy the local cuisine, and roam the streets of the various towns. Around 2 million people head to the island each year, with some of the top spots on Santorini being the Red Beach, the Akrotiri ruins, and the wonderful white streets of places like Imerovigli.

If you're heading down to this island, it's important to note that there are actually several hostels available. These places provide low cost rooms and communal facilities for all guests to enjoy, letting you stay on Santorini on a budget and potentially make friends with other travelers along the way too.
