Starting out in Quiroga, take the LU-P5001 road towards A Cruz de Outeiro. Shortly before getting there, you will see a wooden arrow on the left-hand side of the road that marks the start of the path that you have to follow for 920 metres down to the O Pombar waterfall. On the first stretch of the descent, you walk through chestnut trees along a broad path that gradually turns into a narrow, rocky trail which makes the descent hard going. 

IMPORTANT: You will often need to use your hands to climb down and climb back up safely. This is, therefore, a place that is not easily accessible.
