Description

The Arcediano Path is one of the most historically significant routes in the Cantabrian Mountains: a 13km trail connecting the Sajambre Valley in León with the Amieva municipality in Asturias, climbing 900 metres. The name comes from Archdeacon Pedro Díaz de Lavandera, who in the 11th century commissioned the construction and maintenance of the path to facilitate communications between the two slopes of the Cordillera. For centuries it was the main crossing route before the road through the Beyos Gorge was built. The path starts in the centre of Oseja de Sajambre and climbs through the beech forest to reach the Puerto de la Senda pass (1,510m), from where the most complete panorama of the Sajambre Valley can be seen. The descent towards Asturias passes through oak and chestnut woodland to reach the hamlet of Sería in the Amieva municipality.
