One of the best ways to experience a new place or any place for that matter is to get yourself out of bed and watch the sunrise and wake up a city!
The night before our sunrise mission I went up the mountain for a sunset walk and discovered a whole bunch of churches in the middle of nowhere and where completely quite and tranquil being away from from the hustle of Oia suites.
Just passed the few buildings not he hill, if you follow the rise you come to the edge of this breath taking view of the landscape and cliff faces carving out the island.
This trail I believe can be access via The hiking trail from Oia to Fira is just under 10.5km to do the full length.
Be aware that it is very rocky and there is a lot of cobblestone not he dirt path so be sure to wear appropriate foot wear! Learn from my mistake...
