This is the longest tunnel on the greenway: it's super fun to go through. Be careful: it's a bit chilly!

A very beautiful viaduct, it's a bit impressive and truly unusual on a greenway. The train used to go there, now the bikes go there!

Hello everyone, I'm from Ariège, I decided this year to do the greenway with my dog Emy in both directions. It's a very beautiful walk, however there are some black points: lack of stone benches to deter potential thieves, and on the other hand the large Rimont tunnel which is 803 m long there is no more light. The motion detector does not work. Luckily that day I had my flashlight with me. There is horse excrement everywhere, perhaps one day we will have to ask the riders to pick up their droppings. It's a very beautiful walk.
