S22·E7 Episode 7

In the seventh episode of SuperQuark, the latest documentary in the Ushuaia nature series, which will make us meet extraordinary wild birds, griffon vultures, in the open sky of the Pyrenees. Nicolas Hulot, with his crew, flying almost like a bird without an engine or propeller, relying on a few square meters of fabric and sharing with the large griffon vultures the hot air currents that allow them to glide over cliffs and valleys, will be guided towards another treasure, this time underground: one of the most beautiful marine caves on the planet: Pas de Vallgornéra. It was discovered by chance in 1968, while digging the foundations of a now abandoned hotel. 62 kilometers of tunnels, some of which are completely submerged. It is one of the most important underground labyrinths in the world, which can be explored on foot and by swimming. Once upon a time, tumors were classified based on the organ affected, but increasingly today they are considered a set of diseases, often rare.
