Cuerrias, also known as Les Cuerries de Maza, lies in a valley enclosed by mountain ranges. The Sierra de Ques, Pico Múa and the PR-AS 46 route to Pico La Múa offer different hiking experiences. Specific starting points, trail surfaces and elevations help you choose routes according to their features. Views over the Piloña Valley and the Cantabrian Mountains add to the landscape.
Location and character of the village
The Sierra de Ques is a low mountain ridge west of Infiesto. It separates the valley of the Piloña River from Cuerrias de Maza, a tributary. Cuerrias is the name of the village; the similarly named Cuerrias de Maza is the tributary. The Cuesta de las Cabinas forest belongs to the village of Cuerries and is designated a forest of public utility. Its use benefits the residents of Cuerries. Examples of traditional architecture have also been preserved in Cuerrias.
Trails on the Sierra and routes to the peaks
The “Ruta Sierra de Ques a Beroñes” route crosses the Sierra de Ques on forest tracks and offers views of Les Cuerries and the Cantabrian Mountains. A trail on the Sierra runs almost flat to the west; to the north, views extend over the Piloña Valley and, in clear weather, as far as the sea.
A route description published in 2025 places the starting point of the route to Pico Múa in the small settlement of Cuerrias, also known as Les Cuerries, at 437 m. From there, it heads south along a concrete track to Collado Llamío at 667 m; the IGN map gives the pass name as Rollamío. The trail from Cuerrias then goes via Collada Incosa at 823 m and follows paths slightly northwest to Pico Múa at 987 m. Trail conditions may change. The route description specifies the start, pass names and elevations along the way to the summit.
The PR-AS 46 route to Pico La Múa starts in Frainoquiso and offers views of the Cuerrias Valley. The return route passes through mountain pastures and beech forests. An optional climb, described as easy, leads to Pico Mayor, also known as Bierces.
The routes can be compared by their different features: for Pico Múa, the pass and summit elevations are given; on the Sierra de Ques, the trail surface, westward course and viewing directions provide orientation.
