It is the "Achella reservoir" of Sére-Rustaing and not the "Mun lake", as is usually said. The Sérais are keen to clarify this 😁.

be careful the west side of the lake is passable by mountain bike. On the east side, quite a few trails have become prohibited.

“La Ténarèze” was the prehistoric route which linked the Pyrenees to Bordeaux. It followed, at the crest, the watershed between the watersheds of the Garonne to the east and that of the Adour to the west, without ever crossing a ford or a bridge. Although it is no longer continuous, it can still be followed from the Col de Luquet to Labastide. It is largely tarmac, but there are still some nice gravel sections.
