The greenway from St-Giron to Foix (which I always did in the direction Foix to St-Giron) is the most beautiful part of the greenway which in total goes to (almost) Boussens. It is a slightly hilly section with the most beautiful landscapes!

Very nice walk between paths, forests, small roads with a superb panorama. Small difference in altitude but on a steep and short climb. A very nice little tea room awaits you on arrival in Saint Lizier, a charming little medieval village. We loved it

Formerly an episcopal seat and a stopover on the way to Santiago de Compostela, this quiet village has perfectly preserved its older buildings and is worth a detour.
