The route continues along the Asturian side, descends to Braña Nueva, and without leaving the Puerto de la Ventana road, continues along the Ricabo track. The first few kilometres do not descend from the mountain, they soar over the heights of the municipality of Teverga to the hermitage of Trobaniellu and at the Peñón de San Justo begins a beautiful and enjoyable descent towards Ricabo. In the steepest sections there are patches of concrete, asphalt or cement. The bikes descend at full speed and there is hardly time to enjoy the magic of the autumn beech groves and the rest of the forest jungles that appear while the path sinks into the bottom of a valley that seems endless. The stop at the Fonfría fountain is almost obligatory to fill up with water and then at the Los Garrafes springs, which can be dry depending on the time. The first village is Bueida and immediately Ricabo appears and the first signs for the Senda del Oso Nature Trail. The link from the village road to the Senda is a narrow and quite steep alley, with skill and strength you could climb it on a bike, but it doesn't matter because it is a hundred metres and in a few minutes you forget about the push bike going down a beautiful path towards Rodiles and Santa Marina.
