Leache is a town and municipality in the province and autonomous community of Navarre, in northern Spain. It is one of the many small municipalities that make up the Navarre region, which lies in the north of the country, bordering France to the north and the Basque Country, La Rioja, and Aragon to the west, south, and east respectively.
As a municipality, Leache covers both the town itself and its surrounding municipal territory, and it forms part of the administrative structure of Navarre. The region is known for its Pyrenean landscapes in the north and its drier plains in the south, though the specific setting of Leache within Navarre is not detailed in the available source material.
Beyond its status as a town and municipality within Navarre, little further information is available in the source material about its history, population, or notable features.
