A route close to 30km that runs through the whole of the path along trails and forest tracks, and we will also come across a small section of asphalt as well. In Monte da Chá, it was where a famous battle between English and Spanish troops took place, the Battle of Brión, in the year 1800. In it, it was the people from Ferrol in the area who became the main protagonists, armed with tools of farming and joining the battle together with the Spanish troops to stop the English siege on the coasts of Ferrol, which was intended to deal a hard blow to the Napoleonic expansion and a sharp fall to the Spanish fleet. With a depth of up to 11 meters and about 2 square km of surface, with a sandy barrier of numerous dunes, the Doniños Lagoon is an ecosystem rich in flora and fauna, both aquatic and terrestrial and that also serves as a refuge for a large number of birds, including herons, ducks, gulls and swallows.
