Peña Ubiña

Tuiza de Arriba - Peña Ubiña 4

In Tuiza de Arriba (Lena), situated at an altitude of 1,210 m, the hardest walk towards Peña Ubiña begins. We take the upper path that goes westwards, gaining altitude quickly. As we approach the stream, the great mass of Peña Ubiña emerges on the north face. We continue our walk through the meadows of Boquera del Meicín until we reach Vega del Chagu (1,545 m.). In the surrounding area is the mountain refuge of the Mierense Cultural Centre, which serves as a base for several ascents in these mountains.

We continue southwards up the slope that leads to the Terreos pass (1,933 m.) along a steeply sloping path. From there we can make out the border between Mieres and Lena, as well as the boundary between Castile, León and Asturias, a line defined by a fence of stakes that rises up through the buttresses of Peña Ubiña on one side and Peña Cerreos on the other.

To the south lies the Vega de Riotuerto, where Peña Ubiña Pequeña is located. The great Peña Ubiña extends towards the Ronzón pass, showing the numerous folds of the eastern slope. One of the most direct routes to the summit, for experienced mountaineers, runs along the one closest to us, called Canal de la Fana. Overcoming the rocky reefs and also the unstable boulders, we reach the summit via this channel, where we can see a geodesic cairn and a mountaineer's letterbox.

Another climb, somewhat easier, continues from the border of pastures, skirting the crag at the head of the Vega, to the Ronzón pass (2,000 m.). From there, we climb the meadow and then the overlapping channels to the summit of Peña Ubiña. We continue along the summit towards the north to enjoy the landscape that can be seen from there.
