The road is a bit chilly in winter, near the start of the climb to Cachaudegé and the Portech pass.

The cathedral, which dates from the 11th, 14th and 15th centuries, is a French historical monument. It has a beautiful Romanesque cloister, also classified as a historical monument. It has also been on the UNESCO World Heritage List since 1998.

Magnificent view of the historic center, with the river it makes a magnificent landscape. A bit of a shame that there is the main road not far away with the incessant noise of cars... but it's still worth it!

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

A little past the summit sign of the Col du Saraillé on the way down towards the valley or Aulus is a section where the road opens up in front of your reveiling a stunning view of the mountains with a few houses in the foreground. On the left at the intersection is a little viewing platform with a picnic table where you could relax and take in the view. Or you can also take in the view as you zigzag down the moutain into the valley.

Once you go past the Col de Saraillé sign and down towards Ercé a few kilometers you get an amazing view of the small little village, the valley and the looming mountains in the distance. There is also a viewing point on the left with a small table the shows you the name of each big mountain peak you can see.

Nestled in Ariège, Saint-Lizier offers a dive into the past with its preserved medieval heritage. Ranked among the most beautiful villages in France, it seduces with its cathedral and its frescoes. 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.
