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

The rock overlooks Saint Germain, at the exit of Ambérieu towards Torcieu. A path allows access to the foot of the cliff, from the ruins of the castle of Saint Germain, or from Charvet. Another path allows access to the summit, from Trésin.
