Beginning or end of the railway cycle path „Voie Verte“ St. Girons - Foix or vice versa. A short section also serves to continue to (or from) Palmier. The Foix - Pamier route is neither signposted nor developed. But it can be easily ridden on small side roads.

At the school, there is a tap on an outbuilding. When heading towards Foix, this is the last tap directly on the cycle path that we noticed. It makes sense to refill your supplies here.

A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

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