On a budget, Oia Sunset still earns its price.
Free (viewing); arrive 60–90 min early for a spot
When the light is right it genuinely is one of the most beautiful sunsets on earth, and the village itself is a postcard. The catch: hundreds of people pack the castle ruins and narrow lanes an hour before, and you're elbow-to-elbow holding your phone over someone's head. The magic survives the crowd only if you accept the crowd is part of the deal.
