Follow the cliff walkway near Ferra Pier and take the classic photo route (Fira-Firostefani-Imerovigli). The whole route is about 2 kilometers, taking pictures, about 2 hours on a one-way trip. The blue top on the cover of National Geographic magazine is the low wall behind the Santorini Palace Hotel. Best time for taking pictures: when the sun rises at 8 or 9 a.m. and at 6 or 7 p.m. at dusk, it's a good time for taking pictures of churches.
