Couserans region
Highlight • Natural Monument
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.

Fantastic lake, but it's really hidden and not that easy to reach. The distance says little, it has to be a hard journey.
