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.

The first half is very difficult, all the way up. The second half is easier. But the landscape and water spots are faboluous.
