This spot didn't impress me: "blue lake" is an exaggeration, it's a very small reservoir... lots of people on the banks too.

Smaller pond than lake..more green than blue. Average.

Very nice view

Wonderful historic tower dominating the town of Amberieu in Bugey with its marshalling yard

Blue Lake, as you can imagine, owes its name to the bright shades of blue that its water takes on. The bridge that spans the lake makes it look bigger than it is, but it is actually the dam that creates the lake on the Gardon River.

Indeed the climb above Lac Bleu is very steep unless you have an electric bike which simplifies things

Very nice tour apart from the section after visiting the source where you have to push or carry your bike on very steep and slippery terrain. We would have to find another way to avoid this section. The rest of the course is suitable for all levels.
