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!
