Vacation in Thirassia

Thirassia is considered to be Santorini's "younger sister" as the islands used to be part of the island of Strongyli. After a volcanic eruption, Strongyli broke into smaller parts, forming the famous caldera and a group of islands around it.

Although Thirassia is located right next to Santorini, it remains untouched by the tourist development of its cosmopolitan neighbor. 

Thirassia is great for day trips or short getaways from Santorini, as well as for a relaxing vacation away from the crowds.
