Perhaps one of the most descriptive sites of which is the landscape of the Asón hills. Here, in addition, several paths converge that allow you to cover it almost completely, although when hiking, they can be very technical or even impassable for the bike.

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.
