This is the most obvious hike you can make on the island of Santorini and it will lead you - if you have not discovered them by now - through the sister villages of Fira, Firostefani and Imerovigli, going higher up all the time above the caldera. It then continues through the expanding housing in northern direction and it finally goes to Oia via a really magnificent path. This hike offers many changing views on the volcano, the sea and the caldera. This hike takes two hours and a half (actual walking time), but the total time can reach 4 or 5 hours. It is ideal to leave Firà at about 10am and in this way you will arrive in Oia already between 1 and 2pm. You can then eat in Oia in one of the many bars. In the afternoon you can descend to the little harbour of Ammoudi in Oia. From the bus square in Fira (when you get to Fira by bus) you have to continue to the very busy square of Theotokopoulou. This is the modern centre of Fira with a lot of travel agencies, banks and bars. In the corner, in between the George's Snack Corner and the Pelican travel agency you go left, in the direction of the caldera. You can then take one of the three streets off the right, they all lead towards the higher part of Fira. Once at the Archaeological Museum higher up (this museum is open till 3pm, but not on Mondays), take a left, past the upper station of the cable car. You then go right above the caldera, until the red-brown building higher up that dominates this neighbourhood of Firostefani: it is the P.M. Nomikos Conference Centre, where a lot of exhibitions take place – on the extending corner in front of this building many people take pictures of the marvellous panoramic view. On the left of the Centre you follow the tiled road and stairs, while you enjoy the view – in front of you you can see the even higher situated village of Imerovigli.
