You have to carry the bike to cross the dam, but it's worth the view!

Riding along the Rigole is one of the most beautiful rides I've ever had. It's at least 50km of gentle downhill on a single trail, wooded and therefore shady. I didn't meet any other cyclists and only met five walkers. The corners of my mouth were constantly almost at my ears, absolutely fantastic!

The Mur-de-Bretagne is famous for its steep climb during the Tour de France. The pass stretches for 2 kilometers, with gradients reaching 12%, offering a formidable challenge to cyclists.

Lovely little spot with a stream running past a few benches and a shelter.

Tasty crepes to reward anyone that’s made it up the hill from the south.

Only very recently constructed pumptrack with plenty of smooth flowing lines, on any sort of bike.
