Santorini (or Thera) is the most exceptional island of the Cyclades - and of the entire Greece. It is the biggest of a group of islands, in which Thirasia (the second inhabited island), Old Kameni, Nea Kameni and Aspronisi are included.
With an area of 76 sq.km. (a coastline of 69 km. and circumnavigation 36 nm), Santorini is a small island in size. Its particular position, in key distance between the coasts of Attica and Crete, the favorable morphology (a significant part of the island is cultivated) and the uniqueness of certain natural resources (such as pumice), were, despite all other vicissitudes of the natural environment (shortage of water, earthquakes and volcanic eruptions), the main reasons why Santorini was constantly and rather densely inhabited and why it shined for centuries into the historical context of the eastern Mediterranean.
The habitation system, that had been enshrined during this period, did not differ from the one of other Cycladic islands: the main - and oldest - settlements were built in the maximum security zone, the edge of the caldera, away from the vulnerable lowlands and the coast. Steep paths linked the villages of Fira, Firostefani and Oia with their seaports.
A wide network of cobbled and earth paths spread between the villages, the ports, the vineyards and the beaches. Some of these paths has been preserved until today and composes a unique way to wander Santorini. These paths were recently organized in a large hiking network, which consists of 13 trails. These 13 trails, as well as some other popular routes are included in the application Santorini topoGuide, available for both Android devices as well as for iOS (iPhone and iPad) devices. Santorini topoGuide consists a modern and detailed hiking guide for the island.
