During the mining era, this pass served as a discreet link between mines on either side, and minimal traces of old cart and mule traffic remain, though they don't coincide with the current road. From above, the wind is almost constant, and the view towards the Saliencia lakes has that air of a "natural viewpoint" before the term even existed. It's perfect to mark on Komoot as a key point on your route due to its spaciousness, its somewhat hidden history, and its character as a natural border.

A series of limestone geological thrusts rise above Arbeyales. The waters of the Murias stream have carved an impressive gorge that is one of Somiedo's greatest natural monuments.

San Emiliano is the capital of the Babia region in León, a small town surrounded by mountains and meadows where you can breathe the essence of rural León life. Its stone houses, church, and natural surroundings make it an ideal starting point for exploring Babia's protected landscapes.

The view toward the village of La Peral is very beautiful if the weather is good. Slow down your bike a little and look up for a few seconds.

San Emiliano is a quiet cattle-raising village in the Babia de Yuso at the foot of the imposing mass of the Peña Ubiña massif. The town has all the services and is the starting point we have chosen to begin the climb towards Puerto de la Ventana. In autumn the days are short and we start early, the first rays of the sun barely lighting up the crest of Peña Ubiña. In Torrebarrio we continue along a dirt cattle track to finish warming up our legs and begin the climb towards the border of Asturias along the path of the old Ventana or Santa Fe coal mine. The track has a good surface and the climb is quiet until the Cuspasante sheepfold, passing near the Roguera cabins and beginning the mine slope. The mining operation was inland, the buildings are in ruins, there are remains of the exploitation and enormous slopes of the waste dumps, one of them is at the end of the climb, at the foot of the Peñón de Ventana, and is a panoramic viewpoint of the valley of San Emiliano and a large part of Babia.

Beautiful port with very very hard climbs on both sides.

Impressive views, both for Leonese lands and Asturian lands. The climbs on both slopes are very difficult, but spectacular, and are worth it.
