This protected area takes in two different natural
spaces. On the one hand, the stretch of the Río Grande
de Xuvia with its tributary the Castro; on the other, the
mountain range of Forgoselo.
The old flour factory and mill of the Xuvia bridge signals
the mouth of the river at the back of the Ría de Ferrol,
between the municipalities of Narón and Neda. In its
short river course it crosses damp valleys like that of
Moeche, which has a famous restored castle, and San
Sadurniño where the colour green triumphs in the
landscape. It also receives the contribution of the river
Castro, which reflects the hill where the Naraío Tower is
The O Forgoselo mountain range is outstanding, with its gently undulating forms which are about 500
metres high. The orography and abundant rains favour the formation of very interesting wetlands and
their typical vegetation, such as the Veiga das Lagoas.
