Following the natural course of the Sella River from its source in the Sajambre Valley, the Los Beyos Gorge is about 20 km long. For almost 400 years the existence of a farmer's path that crossed this wild gorge has been known.

The strait is one of the most beautiful points on the route, the pass has some rock and loose stone but it is easy to pass. If there is a lot of water, it can be a little trickier, but in any case, you don't have to climb or do strange things to get through. Moderate difficulty.
