The dramatic promontory of Skaros Rock juts boldly into the deep blue waters of the Aegean Sea, showcasing the rugged volcanic layers of Santorini's caldera. Perched high on the cliff edge above, the sunlit, white-washed buildings of Imerovigli overlook the dramatic drop. The Fira-to-Oia trail ends at the village Oia, which can be seen further away at a distance.
