In an effort to improve safety and reduce the number of mountain rescues, the Cinque Terre National Park has strictly banned flip-flops, sandals, and pumps on its rugged hiking trails. The rocky, uneven terrain of the Italian Riviera can be treacherous, and many tourists have previously attempted the treks in inappropriate footwear, leading to avoidable injuries. Disregarding this ban can result in hefty fines ranging from €50 to as much as €2,500, depending on the severity of the situation and the cost of the rescue required. While you are free to wear flip-flops within the villages or at the beach, you must have sturdy trekking shoes or sneakers with good grip to access the "Sentiero Azzurro" (Blue Path) or any of the other connecting trails. This 2026 regulation is part of a broader push to encourage "responsible tourism" and protect both visitors and the fragile coastal environment.
