Cinque Terre receives approximately 2.5 million visitors per year across five tiny villages with a combined permanent population of around 4,000 people. The overcrowding problem is real. But it's also almost entirely predictable — and therefore almost entirely avoidable, if you know when to go. Tuesday, Wednesday, and Thursday are consistently the quietest days. Monday and Friday see moderate crowds. Saturday and Sunday are the heaviest days without exception. Before 9am or after 4pm is the best time of day to arrive. April and May offer the best combination of weather, light, and manageable crowds. October is the second best month. July and August are peak season.
