Santorini's capital hangs literally: Fira on a 300m rim above the drowned sea — cafés dangling off the cliff, boiling shopping lanes, and the famous cable car dropping to the old port in minutes. The Fira-Oia path (10km/3h) is the island's finest walk — morning before heat, toward Oia for sunset; take the cable car over the 600 mule steps and spare the animals the heat; Fira hubs all island buses — sleep here for economical moving.
