Walk the Fira-to-Oia clifftop trail

This is the best free thing to do on the island, and one of the most beautiful walks in Greece. The trail runs along the caldera rim for around 10km from Fira to Oia, passing through Firostefani and Imerovigli with the blue sea and white villages unfolding beside you the whole way. It takes three to four hours at a gentle pace. Wear proper shoes, as the path is steep and uneven in places, take water, and start early or late to avoid the midday heat. We'll tell you which direction to walk and where to pause along the way.
