This coastal area in Italy, popularly known as the Cinque Terre, takes trekking pretty seriously and for this reason it has a rule that doesn't allow visitors to wear flip-flops, pumps or sandals while trekking in the region. An appropriate footwear will cost you a fine. Before we get to the fine and the reason why, let's see what Cinque Terra is all about. The coastal area comprises of five spectacular villages that are surrounded by the sea on one side and hills on the other. The geography makes it a perfect tourist destination. The rugged and steep landscape attracts a lot of hikers, some rather ill-prepared. The villages of Monterosso al Mare, Vernazza, Corniglia, Manarola, and Riomaggiore are accessible by rugged paths, train and boat.
