You leave the information about places to go towards the viewpoints of Espiño and Punta Revello. Then turns south, Punta da Cruz, to reach one of the most charming coves and quiet of known: that of Margaritas. Southbound Lontreira reached the tip, then the beach of the same name, where we can divert to the projection of the tip Xastellas.
