Take a hike from Fira to Oia
One of favorite things to do in Santorini was to hike along the caldera's edge from Oia to Imerovigli to Fira. The vistas of Oia and the caldera as well as discovering the walking routes from Imerovigli to Fira are the highlights.
Depending on your pace and how frequently you stop, this 6-mile walk might take anywhere from 3 to 5 hours. Since you will be on dirt trails and climbing up and down slopes for a portion of the route, it is more of a hike than a walk, but the majority of the route is paved.
You can go either direction, from Oia to Fira or from Fira to Oia. However, it would be a better experience to walk from Fira to Oia. Doing it this way would make it an overall downhill walk (although you will have to hike up some hills), you get to see the amazing views of Oia in front of you (rather than having to turn around to see them), and you can end in Oia. Spend the rest of the day exploring the village, watching the sunset, and then return to your hotel.
The plunging crater views will take your breath away, so make sure your camera batteries are charged. Explore dramatic cliffside villages and take a small detour to the beautiful Three Bells in Firostefani. This is the most photographed church on the island thanks to its picturesque setting.
