Walking from Fira to Oia with an expert local guide is undoubtedly the most authentic way to experience Santorini’s stunning caldera away from mainstream choices and extreme crowds. On the hidden side of Skaros hill, there is a chapel that literally hangs from the sky above the sea making it an ideal spot to take a break and learn from your guide about the geomorphology, the history, and the people of Santorini. Based on academic research your guide will attempt a retrospective view of how volcanoes have changed the shape of Santorini several times over the years. Learn both about the cultural trends that flourished on the island, ranging from the prehistoric city of Akrotiri to the Venetian and medieval castles, and the recent history of the simple islanders and the fishermen who have been the heart and soul of the island for so many years.
