Couserans is a Gascon country of mountains, hills, meadows, lakes, waterfalls and forests which is entirely part of the Pyrénées Ariégeoises Regional Natural Park. Among its 18 valleys located at the foot of the majestic Mount Valier, some remained landlocked until the recent past, which allowed them to maintain their own identity, such as the Bethmale valley. At the beginning of the 20th century, it was an overpopulated country whose small agricultural plots did not allow families to live, which is why the inhabitants had to show a lot of imagination to find survival activities. This is how some became “bear handlers”, peddlers of vanilla, fake stone, ice. Others became itinerant “raw distillers” or gold prospectors.

Very nice hike. In the shade all along the trail. Perfect for a hike in the heat.

The waterfall consists of a first 100-meter drop that forms a pool at its foot, and continues with multiple cascades that come together to form a final drop. Overall, it is therefore divided into three levels, for a drop of 246 meters. It is undeniably one of the most picturesque and imposing in the Pyrenees.

Beautiful waterfall on the GR 10, which requires a slight detour. You can swim in it or just soak your feet.
