A very picturesque place especially in the spring months where the meadows are in bloom. A few meters away is the Chorrera de Rovellanos, a place that is also worth visiting.

Nice waterfall that deserves to visit. You can get there by several alternative paths, some longer than others but all with a good surface and easy to travel. A recommended place at all times of the year, although spring and autumn are ideal for the colorful landscape.

Recommended, although not for the height of summer, since the first and last parts do not have any shade. It is not an excessively complicated or long route. And the views of the stream are worth it.
