Château Saint-Germain

Highlight • Historical Site

The Château de Saint-Germain, dating from the 11th century, is an old fortified castle whose ruins still remain on the site. It is located 460 meters above the Albarine valley, on a promontory which gives it strategic importance.

As a result, the castle underwent numerous seizures in an attempt to take control of it. A nice place to immerse yourself in history, but also to enjoy the view of the valley.

Allymes Castle

Highlight • Castle

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.

Blue Lake

Highlight • Other

Lots of trails and shaded paths in the woods. On the other hand, it is preferable not to take at the start,
the path above the Abèanches is very steep.
It’s best to start at the source of the roach.
Nice circuit with very few roads.

Lac Bleu on the Gardon

Highlight • Lake

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.
