Alto del Muñón road: A punishing 4WD climb in the heart of Somiedo
Located in the Somiedo Natural Park in Asturias, Northern Spain, Alto del Muñón is a challenging mountain pass at an elevation of 1,789m (5,869ft) above sea level. This rugged track in the Cantabrian Mountains is a legendary destination for off-road drivers, offering deep immersion into one of Spain's most protected and wild landscapes.
The road to the summit is a classic Asturian mountain climb: steep, unpaved, and highly unpredictable. Navigating this trail requires a high-clearance 4WD vehicle and a driver prepared for changing weather and rough terrain. As the route sits within a Natural Park, staying on the established track is mandatory to preserve the stunning environment of the Somiedo peaks.

How do you drive to Alto del Muñón in Asturias?
The drive begins in the small village of Barrio. From there, the road to the summit stretches for 10.7 km through a relentless uphill battle. With an elevation gain of over 1,000 meters, the average gradient of 9.49% is deceptive, as many sections are significantly steeper. The surface is primarily dirt and loose stone, which can quickly turn into a muddy trap after the frequent rains that hit the Cantabrian range. Precise throttle control is necessary to maintain traction on the uneven ramps.
Is the road to Alto del Muñón in Somiedo dangerous?
Yes, the Alto del Muñón road is considered treacherous in several parts. The track is narrow and completely exposed to the elements, with no guardrails to protect against steep drops. Rain and fog can descend in minutes, reducing visibility to near zero and turning the dirt track into a slick, dangerous surface. It is strongly recommended to only travel this road in dry conditions. Due to the deep ruts and potholes, a high-clearance 4WD vehicle is not just recommended, but essential.
Can you drive to Alto del Muñón during the winter?
While the road is theoretically open year-round, winter in the Somiedo Natural Park is harsh. Heavy snowfalls and ice often make the pass impassable even for the most capable off-roaders. During bad weather periods, the road may be officially closed for safety. Always check the local weather forecasts in Pola de Somiedo before departing, as being caught in a storm at 1,700 meters can be life-threatening.
What makes the scenery at Alto del Muñón special?
The reward for the difficult climb is a stunning 360-degree view of the Cantabrian Mountains. The Alto del Muñón is a land of great beauty, where you can see the unique "teitos" (traditional thatched huts) and potentially spot local wildlife like brown bears or vultures. The contrast between the rugged 4WD track and the pristine green valleys of Asturias makes this one of the most awe-inspiring drives in Northern Spain.
