The waterfall cascades down a steep rock face, formed by large boulders and outcrops of dark and gray stone. The water, a brilliant white color, splits into multiple streams as it descends, creating a multi-layered effect. Around the waterfall and along the rocky slopes, vegetation is sparse but tenacious.

If you run the PR3, this point is well before the halfway point, but at least after the biggest climb -> top spot for the lunch break

Beautiful spot on the Ribeira de Arnal, just to watch the water rippling or to jump in. There is a road with a parking lot directly above.
