The sunset in Oia is something one has to see in his or hers lifetime. Photos just don't do it justice. For this particular view you have to be on top of the castle which at sunset time, as you can imagine, it's packed with people.
They start saving a seat at 7pm even so be there early. If not, try to squeeze your way in, between lovers and passionate photographers equipped with heavy gear to get the best shot. My luck was my husband who managed to find a small pocket and shove me in.
While it's happening people are not making a sound, they are almost holding their breath and the only thing you hear are the camera clicks.
