Oia is a wonderful coastal town on the northwestern tip of Santorini, a Greek Aegean island. You can reach here by the local bus at Fira bus station 12 kilometers away for around €1.60 and it takes around 30 minutes. The town had whitewashed houses carved into the rugged clifftops, and overlooks a vast caldera filled with water. Walking along the narrow streets and alleys, visitors will come across a number of small cafes and boutiques. The whole village is lined with pretty little churches, windmills and gleaming white houses that make a lot of spots a good photoshoot.
