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.

The food is very good, and the people who run it are very attentive. I recommend contacting them via WhatsApp to make a reservation.

You have to get up early to park your car. Always take the summer road, as the winter road is closed.

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