Main cape in Bergantiños, together with those of Santo Hadrián and Nariga. The cape of Roncudo owes its name to the echo of the sea as the Atlantic crashes against this outcrop.
The Roncudo lighthouse constantly warns the maritime traffic on the lighthouse of the dangers of this stretch of sea, a veritable graveyard of shipwrecks. The crosses that stand on the cape are a reminder of the many fishermen who have lost their lives to the endless ocean. It is a great place for birdwatching with many seabirds and migratory species passing through. Most common are seagulls and cormorants. It is also famous for its percebes which grow on the wave-battered rocks.
In these rough waters, it is vital to know the tides before venturing out to sea. The moon and the waves control the destiny of the percebes and the percebeiros - the men and women who collect them. Many people have lost their lives carrying out this work, betrayed by the vagaries of the sea. The tides here can vary by as much as four metres and so it is generally at low tide - and conditions permitting - when the percebes are above the white waters of the waves.
