The Faxón water channel is a tributary of the river Avia, which flows into it from the Pena Corneira mountains and forms two independent waterfalls. To reach the second waterfall, go to the post office in Leiro and continue along the road for about 50 metres, where you take a paved detour to the right that goes to Eira dos Mouros and Rubial. The waterfall is to the right of where you cross the river.
