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

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!

Superb forest track for a very pleasant descent (towards Fougaron), very smooth but with just enough rocks to keep you focused. Be careful, the last section (junction towards Fougaron) must see a lot of forestry vehicles pass, because the path is much less pleasant, very uneven and rocky. Fortunately it's not very long, but it's better to have good brakes.
