At around 4 Pm I boarded bus to Oia Well without hesitation Oia is most, most beautiful town in Santorini. Though accommodation prices are nightmare in Oia, do make day trip here. It’s most picture perfect place I’ve seen in my life. Even though it was cloudy & rainy day. Sun showed up just 30 mins before sunset and I got to witness the sunset I had always dreamt of.Bus leaves from Oia to Fira at 6; 30. If you miss don’t worry there are 2 more buses which leave an hour apart.
