Nice route and without too much complication. If it rains you will find mud at some points, so you have to come prepared but nothing to write home about.

Viewpoint and natural enclave on this coast of dexo. Seixo branco is an outstanding white quartz vein that draws attention among the cliffs to the point of serving as a navigational reference for sailors. It can be seen from the city of A Coruña. From this point you cannot see but you can enjoy impressive views of the abrupt and wild coast, the Atlantic Ocean and its entrance into the Burgo estuary and the city of A Coruña in front.
