This route runs along a large part of the encoro de Vilasouto, built in 1969 on the basin of the Mao River. 

Starting from the village of Eirexalba we can take the asphalted track that goes around the reservoir or follow a parallel path that goes closer to the lake. This is a simple walk, very suitable for children, which has picnic areas and, in its last part, offers us a forest where we will find a wide variety of trees such as chestnut, birch, cherry, ash, alder, poplar, willow, etc. 

It is an ideal place to relax or to practise a sport such as fishing, which is authorised all year round for the capture of certain species.
