Pico Bierces – Pico Mayor: Hiking Asturias’ Quiet Cantabrian Summit

Why Pico Mayor Stands Out

Pico Mayor, also known locally as Pico Bierces, rises to 1,075 metres in the modest Sierra de Peñamayor range. Its rounded granite summit delivers 360-degree panoramas that stretch from the Picos de Europa to the Bay of Biscay on clear days. Unlike the busier coastal peaks, this summit remains largely the domain of local walkers, offering a genuine sense of solitude in green Asturias.

Reaching the Trailhead

Most visitors start from the village of Lieres or the hamlet of San Miguel de la Barreda, both roughly 25 minutes by car from Oviedo. The final approach uses narrow asphalt roads that climb through chestnut woods; park at the small turnout near the old mine road. Public transport is limited, so a taxi from Pola de Siero or a rented car is the practical choice.

The Standard Route

The classic ascent follows an old mining track that becomes a clear footpath after the first kilometre. The walk is 8 km round-trip with 550 m of elevation gain and takes three to four hours for most hikers. The final 200 m to the summit is a gentle scramble over lichen-covered slabs; no technical gear is required in dry conditions. On the way up you pass abandoned galena mines and spring-fed troughs where cattle graze.

Flora, Fauna and Views

Lower slopes are covered in oak and beech that give way to heather and gorse near the top. In spring, wild daffodils carpet the meadows. Look for griffon vultures circling the ridges and, in autumn, red deer rutting calls echoing across the valleys. The true summit is marked by a small stone cairn and trig point; on the clearest days you can trace the entire coastline from Gijón to Ribadesella.

Best Time to Visit

Late spring through early autumn offers the most reliable weather. Snow can linger into April on north-facing slopes, and winter storms bring high winds. Weekday mornings are quietest; weekends see a modest influx of families from nearby towns.

Combining Your Visit

After the hike, many travellers continue to the cider houses of Nava or the Romanesque church of San Salvador de Valdediós, both less than 30 minutes away. The coastal beaches of Villaviciosa are also within easy reach for a post-hike swim.
