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]).

A very interesting and familiar place. I tried to get to the Sumidero de las Palomas, but it was impossible for me to get there, I would have needed not some walking sticks, but a machete!

Divided into the west and east beaches, their name comes from the caves found on the islet that divides them. A very popular beach in summer although it offers an ideal escape at any time of the year.
