Fira is the capital of Santorini. On the caldera side you get one of the best views of the island and the activity level is enough to keep you entertained for hours. There are cafes, bars, restaurants, all with views and some with several levels of patios and balconies to make the most of the space they have and the fact that when there are several cruise ships sitting below the town is packed with tourists. Just walking down the street is laborious. The cafes fill up with tourists. Hundreds of them. Thousands of them. Like Leiningen vs the Ants they are unleashed on the town consuming everything in sight, stopping only to take photos of themselves with the view behind them. But the ships come and go and when they go they take the population with them and Fira can actually be a pretty nice place.
