Taramundi is part of the Turia Valley or "Valle del Turia", a small valley on the western border of the Cantabrian Mountains in the northwest of Spain which is close to beaches and is divided by two counties: Asturias and Galicia. It has 3,910 inhabitants and is 200 m above sea level.

The climate in the region is pleasant throughout the year. As with the rest of northern Spain (or the Green Spain), the climate is more variable than the southern parts of Spain and is characterised by an Atlantic climate.

The Turia River gives its name to the valley. The valley is surrounded by hills and mountains, including, Sierra de Piedrafita (900 m), Sierra de Ouroso (1033 m), Sierras de Dendin (900 m), Sierra de Teixedais (900 m) and Sierra de Eirua (700 m). UNESCO Biosphere
