Braña de Murias Chongas: A technical 4WD track in Somiedo
Braña de Murias Chongas is a high mountain pass at an elevation of 1,650m (5,413ft) above sea level, located in Asturias, Northern Spain. The track is situated within the Somiedo Natural Park, a protected area known for its steep limestone peaks and complex terrain near the border with Castile and León.
The road to the summit, designated as Camino PR AS-15.1, is a mountain track composed of loose gravel and rocks. It is strictly a 4x4 route that requires high ground clearance due to the presence of deep ruts, water erosion, and large embedded stones. Driving this section demands constant attention to line choice to avoid mechanical damage.

How is the drive from Valle de Lago to Murias Chongas?
The ascent starts from the village of Valle de Lago. The route covers 6.2 km with a total elevation gain of 410 meters. While the average gradient is 6.61%, the difficulty lies in the surface condition. As seen in the area, the track is heavily affected by mountain runoff, creating deep channels and exposing bedrock. Traction can be an issue on the steeper ramps, especially when the soil is damp.
What are the main hazards on the PR AS-15.1 road?
The main risks on this track are the exposed drops and the lack of space for passing other vehicles. The terrain is unpredictable; heavy rain can wash away parts of the path, leaving deep potholes and loose scree. Weather in the Cantabrian Mountains changes rapidly, and fog often reduces visibility to a few meters. In winter, snow and ice make the 1,650m pass impassable for standard vehicles, and the track may be closed during severe weather events.
Can you drive to Braña de Murias Chongas all year?
Although the track is technically open, driving is only recommended during the dry months. The high altitude means that patches of snow can remain on the track well into late spring. Because this is a protected Natural Park, drivers must stay strictly on the Camino PR AS-15.1. Off-road driving outside the established track is prohibited and heavily fined. Always check local conditions in Somiedo before starting the climb.
