It is imperative to do at least once the amazing itinerary from Fira to Oia. Only in this way will you have experienced the absolute grandeur of the island. In Fira you should ask for the old path leading to Oia. Make sure you set off early in the morning to avoid the big heat or in the evening so that you reach Oia in time for the sunset. It will take you about 3 hours to get there. You will pass by Katholika of Fira with the beautiful mansions. Walking down to the caldera you will meet the Catholic Cathedral. Going on towards Firostefani-Imerovigli, you will see Agios Nikolaos and get to Skaros. Walk up to Theoskepasti, a picturesque little church. When getting to the asphalted road, there is an uphill leading to the Profitis Elias chapel. From here you have the best view.
Walk along the stone path starting from the ‘Krifo Sholio’ in Pyrgos up to the monastery of Profitis Ilias (at some point the path is interrupted by the street and then starts again). At this spot you will get overwhelmed with the view, the height, the landscape, the sea horizon of the other side of Santorini. It takes about hald an hour to get here.
