The estuary of O Barqueiro is one of Galicia's smallest and also one of the most beautiful. The furious coming together of the Atlantic Ocean and the Cantabrian Sea takes place in the cape of Estaca de Bares, the Iberian peninsula's northernmost point and an excellent bird watching location. Every year in autumn thousands of birds fly over this coast and over the island of Coelleira, where the remains of an ancient Templar monastery becomes their secret refuge.
