Arenillas beach is a small beach of fine sand next to the Oriñón estuary. The beach disappears at high tide, but at low tide, in addition to the beach itself, there is also a strip of sand that joins it with Oriñón beach. In addition, the beach, at low tide, is a popular area with surfers, although you have to be careful with the underwater currents. In fact, on the left side of the beach you will see an area where the buoys restrict access due to currents.

Viewpoint between Oriñon and Liendo on the old road. You have to walk about 200 meters with some unevenness to the viewpoint itself. There are beautiful views of all of Liendo and the mountains in the area. It has two wooden tables in different areas.
