Located between Levanto and La Spezia, this region features five scattered picturesque villages sharing the title of a UNESCO World Heritage Site since 1997. The area, also including a protected marine area, became a national park or Parco Nazionale delle Cinque Terre in 1999. The villages of Monterosso, Vernazza, Corniglia, Manarola and Riomaggiore are separated from the rest of the country by mountains, olive groves and dry-stone-walled vineyards. The area's status as a national park probably saved it from enviromental destruction and the tackiness of mass tourism. Entrance for cars and motorbikes is not allowed to the villages, which are connected by train, and are each some five minutes apart. Electric buses provide the transportation within the villages. The villagers have also profited from the area being proclaimed a national park with free health screenings, subsidised child care and free shopping service for the elderly. The pesto made from locally grown basil, garlic and pine nuts can be tasted in village restaurants, as well as other local products such as white wine, fish and lemons.
