Full route track - The green line it’s the path from ”the Hole” to ”Casas de Bernia”, almost half way to the ”Fort of Bernia”. — *Full route track - The green line it's the path from "the Hole" to "Casas de Bernia", almost half way to the "Fort of Bernia".*

After crossing "el Forat" ("the Hole", a narrow tunnel through which you have to crawl, which connects the northern and southern slopes of the Sierra de Bernia), I am chatting and explaining some data about the history and formation of this mountain range.

It's interesting to know that when doing this hiking route (PR-CV 7 of Sierra de Bernia) you are walking on land that was under the sea for millions of years; specifically, you walk on part of the seabed of the Tethys ocean when, back in the Mesozoic era, dinosaurs populated the earth (and the seas).

Limestone and sediments accumulated over millions of years at the bottom of the sea, due to the precipitation of small carbonate crystals dissolved in the water along with the shells of planktonic organisms and mollusks (1).

It's known that these limestone mountains that you see in the video and that make up the Sierra de Bernia mountain range (maximum height of 1,100 meters) were formed in the alpine folding of the Miocene (Cenozoic), and are full of fossil skeletons of animals that inhabited the Tethys Sea more than 20 million years ago.

As an interesting fact, the Sierra de Bernia is the closest vertical kilometer to the sea in the entire Iberian Peninsula.

Sharing with you now some YouTube Shorts from the beginning of the hiking route.
