When many people think of Greece, they picture the well-known and widely visited islands such as Santorini, Mykonos, Rhodes, and Crete—and who could blame them? These islands are so beautiful that they almost feel like they’re straight out of a dream. But while it’s easy to overlook some of the lesser-known Greek islands, their underrated beauty deserves just as much praise as their more popular counterparts. Here are the top 10 most beautiful islands in Greece you’ve never heard of.

1) Kassandra

Kassandra is one of the most beautiful islands in Greece. It’s located west of Chalkidiki and is the largest of the Northern Sporades, which are a group of islands off the east coast of mainland Greece.

2) Skiathos

Skiathos is a small island that is part of the Sporades group and the closest to Skiathian mainland. It has a long and interesting history which includes many famous visitors such as Lord Byron, Mark Twain, Aubrey Beardsley, and Queen Victoria. The locals are great storytellers and you’ll hear stories of ancient heroes while enjoying a coffee or wine at one of the cafes.

3) Amorgos

Amorgos is a Greek island located on the eastern side of the Aegean Sea. One of the most interesting aspects of this island is that it does not have any cars on it, and instead, relies on donkeys for transportation. This lush green mountainous island is full of ancient ruins and some of the clearest, bluest water you will ever see!

4) Andros

Andros is a Greek island with the highest mountain in the Cyclades. The island’s population was around 4,500 inhabitants as of 2011. The capital city is Kyriamadi (pop. 1,900). Andros has one of the best-preserved villages on the Aegean Sea, which are often featured as postcards.

5) Siros

Siros is a small island in the North Aegean Sea that’s popular for its olive and grape plantations. It has a population of about 1,200 and is known for its vast, picturesque landscapes. Siros’ beaches are filled with pebbles, unlike the typical white sand you see on other Greek islands.

6) Telendos

Telendos is a small island off of the coast of Santorini, and it is a bit less touristy than some of the other islands. The beaches are clean and clear, with plenty of shade for those who want to avoid the sun. Telendos also has an abundance of wildlife and vegetation that you don’t see on Santorini or Mykonos.
