Even on a tight schedule, Oia Sunset earns the hours.
Allow 1.5–2 hours incl. waiting.
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.
