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

Nice route of beautiful paths in the undergrowth, some singles without difficulties, some viewpoints on the heights of Vaux, Lagnieu. Attention ⚠ small single going up between Vaux en bugey / Bramafan very steep and narrow, the second part of the descent after Bramafan is technical slope and slippery rocks.

Col named after the small village located lower down, magnificent. To be made during a detour to continue on the Col de Portes.

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.

Lac Bleu, as you can imagine, owes its name to the bright shades of blue that its water takes on. The bridge over the lake almost makes it look bigger than it is, but in fact the bridge is the dam that creates the lake on the Gardon River.
