The climb to Alto de Chavadoira on the southern slope, from Pola de Allande, is one of those ascents that best defines the character of western Asturias: narrow roads, mountainous surroundings, a steady gradient, and the feeling of being in a place far from the noise. It's not a mountain pass with impressive numbers, but it is one of continuity. The road itself is in good condition, but its narrowness and the presence of blind curves require caution, especially on the descent. Traffic is almost nonexistent, which enhances the experience, but doesn't eliminate the need to remain alert at all times. In terms of weather, the pass reflects the reality of the Asturian mountains: humidity, fog, and temperature changes are frequent, so it's advisable to always wear appropriate clothing even if the day seems stable at the start.
