Beautiful body of water, but the track along the west of the lake was flooded and therefore impassable in March 2026... impossible to go around. So be careful.

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 castle overlooks the Ain plain. A few benches are available for relaxing while admiring the view. It's possible to walk around the castle by continuing along the path past the entrance. It's accessible with a paid ticket, and opening hours vary depending on the season.

Geological curiosity, the rock opens in two over 100m long. It is possible to go down to the bottom from the east end and you find yourself 10m below.

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.

Allymes Castle is the only example of a medieval fortress in Bugey. Overlooking Ambérieu-en-Bugey, it is built on a mountain 650 meters above sea level. Its geographical location offers a breathtaking view of Savoyard Bresse and Dombes. As a strategic stronghold, it protected the entrance to Savoy, which was an independent state at the time.
