The northern village of Oia  is  the most popular place to watch the sunset in Santorini. One prime spot can be found near the old castle to the west, overlooking the iconic blue domes of the Agios Spyridonas and Anastaseos churches in the middle of town. Others can be found by the famous windmills in the north or along the hiking trail leading east. With the most famous spots, you’ll have to get there well in advance to claim the best spot, and you’ll still have to compete with hundreds of other people who want to enjoy the magnificent view
