Why Pico Tonón Rewards Visitors
Pico Tonón rises above the valleys of western Asturias, offering hikers a relatively uncrowded summit with sweeping views across the Cantabrian range toward the Picos de Europa on clear days. The mountain’s gentle upper slopes contrast with steeper approaches from the south, creating a rewarding half-day objective that showcases the region’s lush beech forests, limestone outcrops and seasonal wildflowers.
Getting There
The trailhead lies near the village of San Antolín de Ibias, reached by the AS-15 road from Cangas del Narcea. From the village, a narrow paved lane continues toward the Collado de Tonón parking area; the final section is gravel but passable for ordinary cars in dry weather. Public transport is limited, so most visitors arrive by car or arrange a taxi from Cangas del Narcea, roughly 35 minutes away.
Trails and What to Do
The standard route follows an old stockmen’s path that climbs steadily through mixed woodland before emerging onto open pastures. After about two hours the path reaches the broad ridge leading to the summit cross. On the way, look for griffon vultures riding thermals and, in early summer, fields of asphodel and gentian. The round-trip distance is approximately 10 km with 700 m of ascent; allow four to five hours at a comfortable pace. Experienced walkers can extend the day by continuing along the ridge toward neighboring Peña Trevinca.
Best Time to Visit
Late spring through early autumn provides the most reliable conditions. Snow can linger into May on north-facing slopes, while July and August bring long daylight and abundant wild berries. September often offers stable weather and fewer insects. Winter ascents require mountaineering equipment and local knowledge of avalanche risk.
Nearby Attractions
After descending, spend time in the Ibias valley sampling traditional cider houses or visit the nearby Muniellos Biosphere Reserve, one of Spain’s largest remaining oak forests. The medieval town of Cangas del Narcea, with its historic monastery and wine route, makes an excellent base for combining mountain days with cultural exploration.
