Oia's Cliffs and Harbors

Why go

The geography explains both the views and the effort of exploring. From the upper paths, the caldera opens toward Therasia and the volcanic islets. Ammoudi lies below the western side and Armeni below the southwestern side, so a walk to the water involves a steep return climb.

Useful to know

• Plan the rim lanes and a harbor descent as different walking commitments.
• Expect exposed sun and wind on the cliff edge; the narrow village paths offer little room to pass at busy times.
