It is a very narrow gorge carved by the river, creating spectacular landscapes, especially in the thawing season when numerous waterfalls and waterfalls are formed.
The Alba Route has become one of the most emblematic elements of the Redes Natural Park due to its beauty and easy walking, with no steep gradients.
In Soto, a beautiful village of granaries, corridors and chestnut balustrades, just two kilometres from Rusecu/Rioseco, the municipal capital, you take a wide road along which road traffic has been restricted exclusively to agricultural vehicles.
This road was used in ancient times by shepherds and muleteers to reach the neighbouring Aller valley. Later, this route was used for the evacuation of iron from the Carmen mine. This route, also called Foces del Llaímo, runs parallel to the river Alba, and is a round trip, with an approximate duration of four hours, suitable for the whole family.
The Alba Route is in the municipality of Sobrescobio, running parallel to the stream of the same name, from the Cruz de los Ríos to the El Alba fish farm.
