Xistral Mountain Range is part of the massif that separates the Terra Chá valley of the sea; the other mountains are Toxiza and Carba. It occupies the councils of As Pontes de García Rodríguez, Abadín, Alfoz, Mondoñedo, Muras, Ourol, O Valadouro, Vilalba, Xermade, Xove, Viveiro and Cervo.

Xistral Mountain Range flows into the Cantabrian Sea, crossing the Terra Chá valley through Abadín, and the rivers Sor and Eume. Xistral Mountain Range and the banks of river Sor have been declared Nature Reserves.

This is the area of Galicia which receives less sun, and the fog that oftenly covers the high hills of the mountains leaves plenty of rain that soaks their extensive pastures, inhabited by free horses and endemic species. Notice the presence of natural pools and forests (alders, ash trees, willows, holly trees...).

Referring to fauna we can mention many lizard species (Lagarto das Silvas, Lagartiza das Brañas, Lagartixa da Serra...) and bird species (Becacina Craba, Picaouro, Picanzo Vermello, Picanzo Real, Papuxa Montesa...).

Wind breaks all year in the mountains where we can find an unique mineral called Quartzite of Xistral.
