Baliarrain is a town in the province of Gipuzkoa, within the autonomous community of the Basque Country in northern Spain. It is one of the small municipalities that make up this part of the Basque region, situated in the north of the country near the Bay of Biscay coast.
Like other settlements in Gipuzkoa, Baliarrain lies within a province known for its green, hilly terrain and its distinct Basque cultural and linguistic identity. The town is administered as a municipality, the basic unit of local government in Spain.
Baliarrain is a minor municipality rather than a large urban centre, and detailed information about its population, history, and landmarks is limited. It shares the general characteristics of the rural and small-town communities found throughout Gipuzkoa.
