No special access issues
From Vecindario drive up to Santa Lucía and 4 kms before this town there is a split on the road that takes you to "La Sorrueda" (you can see a cemetery from this point). After about 5 kms there is a split to the right that you need to take and drive all the way till it finishes by the riverbed, park wherever you can and walk to the riverbed, then walk up river till the first sector, about 5 mins walk
