In each horseshoe of the road you will have a panoramic point towards the imposing waterfall of more than 70 meters that physically marks the source of the Asón river. A wonderful landscape that deserves a few minutes to enjoy it.

Both the waterfall and the environment that surrounds it are simply wonderful. Easily accessible, this waterfall is a waterfall of about 70 meters with a natural pool at its feet. A true paradise that deserves to be visited at any time of the year, although it is recommended in spring-summer.

Excellent cavity, easily accessible, at least to some extent. I had the front and even so I did not enter more than a few meters, due to the wet terrain and the very strong wind that came from the interior.

Always check specific trail regulations or park notices before heading out, as some areas might have restrictions during certain seasons or for conservation purposes.
