Top 10 Natural Monuments around Ruiloba

The Bolao Cliff is a stunning natural setting on the coast of Cantabria, Spain, between Cóbreces and Toñanes. It is famous for the El Bolao waterfall, which falls directly into the sea, and for the ruins of a medieval mill. The landscape combines the green meadows with the rugged Cantabrian Sea coast, offering spectacular views.

A beautiful coastal hike with views of the Picos de Europa, the Sierra de Cuera, and, in the distance, the coast of Asturias, approximately 60 km away. The hike starts at the La Santuca restaurant (recommended) in the tiny village of Arroyo (Santillana).

The Altamira Cave covers an area of more than 5500 m². It was used from 33,600 BC until the entrance collapsed in 11,000 BC. The particularly impressive ceiling paintings are dated to the period 16,500 to 13,000 BC.[3] The cave was discovered in 1868 by a hunter due to the disappearance of a hunting dog, who immediately reported the discovery to the lord of Santillana,[2] the naturalist Marcelino Sanz de Sautuola (1831–1888). The paintings were discovered by Sautuola's five-year-old daughter Maria, who was able to walk upright through the cave and made out images of "cattle" on the ceiling.[2] Marcelino began systematically digging in the cave in 1879[2] and published a short description of the "prehistoric objects in the province of Santander". Even the Spanish King Alfonso XII was invited into the cave. However, the academic world doubted the authenticity of the cave paintings.[2] The French prehistorian Émile Cartailhac described the paintings as a "vulgar prank by a scribbler" that he and his contemporaries did not even want to look at. The discovery had to wait almost 23 years for recognition. It was only when similar paintings were discovered in the Font-de-Gaume cave near Les Eyzies-de-Tayac-Sireuil in the Dordogne department (France) in 1901 that the attitude of French researchers and Cartailhac, who became the symbol of archaeological ignorance, changed. Cartailhac apologized posthumously to the Marquis de Sautuola in an essay in 1902 ("Mea culpa" d'un sceptique[4]).

End of the road stop but worth it because you can see the inlet perfectly and enjoy fantastic views of the sea. Supposedly there is a small port that was used in the past as an old zinc ore loading dock for the nearby mines, but I didn't feel like investigating it too much because as @oscargynko says there is quite a slope and a lot of rocks... perhaps there is a more viable way to go down another way.

Very well done museum, very worthwhile

The Oyambre Natural Park has an extension of 57 square kilometers and consists of enormous beaches surrounded by an extensive forest mass. The Picos de Europa mountain range in the background is impressive. It is a territory of great ornithological richness, located mainly in its estuaries and marshes.

The Oyambre estuary or La Rabia estuary is an estuary located between the municipalities of San Vicente de la Barquera, Valdáliga and Comillas. Seventeen species of birds use these fertile waters to feed and rest in winter. The mallard, common teal and great cormorant are representative of this ecosystem.
