Playa de Gulpiyuri

Playa de Gulpiyuri is a flooded sinkhole with an inland seashore placed near Llanes, in Asturias Northern Spain, around 100 m from the Cantabrian Sea. Roughly 40 meters in length, it's far fully tidal due to a series of underground tunnels carved with the aid of the salt water of the Cantabrian Sea which permits water from the Bay of Biscay to create small waves. It is a famous tourist vacation spot, natural monument, and a part of Spain's Regional Network of Protected Natural Areas.

A herbal monument is a herbal or herbal/ cultural feature of extremely good or specific price because of its inherent rarity, representative of aesthetic features or cultural importance. "Areas are set apart to protect a particular natural monument, which can be a landform, sea mount, submarine cavern, geological feature which include a cave or maybe a living function including an ancient grove. They are generally pretty small blanketed regions and frequently have high traveller cost."
