The capital of Santorini, Firá (Thíra) is made up of whitewashed cubic houses and terraces, winding lanes, little squares, and blue-domed churches perched on the cliffs 300 meters above the caldera.

 From the small port of Skala, Firá can be reached either by walking or riding (mules are for hire) up the steep and winding stepped path (587 steps) or by taking the cable-car. It can also be reached from neighboring towns via the Fira to Oia scenic trail that takes you along the caldera cliff.

Ferries dock at the port of Athiniós, connected to Firá by road, while cruise ships put down anchor in the caldera, and passengers are transported to Skala by tender.
