It is said that the barnacles that grow at Cabo Roncudo near Corme are the best in the world. This is so due to the natural conditions in which they grow: temperature, salt levels, position of the rocks against the waves and levels of sunshine. Besides this, since the 80s there have been plans in this area, in order to assure that this resource is used in a sustainable way and this has also contributed to increase their quality. I am not sure if those plan have always been respected, but at least in the last few years it seems so.
