About Playa de Regatón Archived on July 12, 2013 in Playa del Regatón is located in the western area of Laredo. This beach is where you can best enjoy the sunsets. There are few beaches in Cantabria with this orientation, which makes it a privileged place to enjoy spectacular sunsets when the sun sets. Visiting this beach is highly advisable if you are looking for tranquility and do not mind doing without the sea waters. Since this beach is part of the mouth of the Asón River and the water comes from this river, although at high tide the sea water merges with the waters that come down from the top of the Asón Valley.
