Oia is hands down the most famous and beautiful town on the Island. However, it is admittedly on the touristy and crowded side particularly during sunset. Therefore, an early morning stroll in this town is advised.
Its charming houses, blue domed churches, and sun-bathed verandas facing the Caldera contain unparalleled beauty. Its geographical location also makes it a prime location for indulging the sunset whether from one of its many verandahs, or from a boat below. If you have not been to Oia, you have not been to Santorini.
