The Cinque Terre is not located on an ocean, but rather on the Ligurian Sea, which is an arm of the Mediterranean Sea. This rugged stretch of the Italian Riviera in the Liguria region consists of five historic villages: Monterosso al Mare, Vernazza, Corniglia, Manarola, and Riomaggiore. The Ligurian Sea is bounded by the Italian coast to the north and east and the islands of Corsica and Elba to the south. It is known for its deep blue waters and dramatic cliffs that drop directly into the sea, which is why the villages were historically accessible mainly by boat or narrow mule tracks. While it is part of the broader Mediterranean basin, the specific name "Ligurian Sea" is used by locals and geographers to describe this specific northern corner. The sea plays a vital role in the region's identity, influencing everything from the salty microclimate that allows lemons and grapes to thrive on steep terraces to the traditional seafood-heavy cuisine, such as the famous salted anchovies of Monterosso.
