To walk the trails of Cinque Terre in 2026, the most critical item is sturdy footwear with good grip, such as trail runners or hiking boots. The park authorities have strictly banned walking the trails in flip-flops, sandals, or pumps; travelers caught wearing improper footwear can be fined up to €2,500 because of the high risk of injury on the steep, uneven stone steps. You should wear moisture-wicking layers, as the coastal humidity can be intense even in the shoulder seasons. Lightweight hiking shorts or leggings are ideal. Since there is very little shade on the Sentiero Azzurro (Blue Trail), a wide-brimmed hat, polarized sunglasses, and a high-SPF sunscreen are essential. Even in summer, carrying a lightweight windbreaker is smart for the windy segments between Corniglia and Vernazza. Finally, always pack a swimsuit and a travel towel in your daypack, as you will likely want to cool off in the sea at Monterosso or the harbor in Manarola after your hike.
