A small mountain village in the heart of the Riaño Mountains, surrounded by green meadows and mountains that are blanketed in snow in winter. Its stone houses with slate roofs preserve the traditional Leonese architecture. The name, according to local lore, comes from an old royal stay during a hunt in the area. The Buerga River flows peacefully through it, and at dusk, the sound of the water and the smoke from the chimneys give the valley a fairytale atmosphere.

It's worth stopping to admire the views and take a photo. An accessible port where you can see a palloza up close. I loved it; the descent to León was super cool!
