This waterfall is in San Sadurniño, just below the 14th century Naraio castle, the ruins of which can be visited.

Park next to the castle and head down a dirt track to skirt around the bottom of it on the way to the waterfall, which is on the River Castro, a tributary of the River Xubia. 

This waterfall plunges from a height of 6 metres and is quite seasonal, as the flow varies a lot depending on the time of the year.
