Are there neighborhoods to avoid in Santorini?

Santorini has no neighborhoods that require avoidance for safety reasons — it is one of the more reliably low-crime destinations in the Mediterranean. The real issue is overcrowding. Fira's central commercial strip and Oia's sunset-viewing area along the caldera path become genuinely unpleasant between roughly 11 a.m. and 8 p.m. from June through August, less because of danger and more because cruise ship day-trippers arrive in waves of several thousand. If you're staying overnight, you already have an advantage: mornings before 10 a.m. and evenings after 9 p.m. return those places to something resembling their actual character. Firostefani and Imerovigli, the quieter caldera villages immediately north of Fira, offer nearly identical views with a fraction of the foot traffic. The industrial port area near Athinios is purely functional and worth skipping unless you're catching a ferry. Perissa and Perivolos on the black-sand beach coast are casual and relaxed, with nothing to worry about.
