Nice place to cool off on a small pebble beach just before the bridge when it's a heatwave!

The coolness in these gorges is much appreciated when it's close to a heatwave on the plains! And the wild atmosphere of the small road through these gorges (before reaching a busy road for a beautiful descent) is good (a little "kick in the ass" to get out!).

A tourist attraction in this area is Lake Paladru, which stretches from the village of the same name in the north to Charavines in the south. If you walk around the lake from a distance rather than on the paths directly along the shore, the hills offer some very beautiful views of the landscape. But not only that: on the outskirts of Bilieu – on the eastern shore of the lake – we pass a small sacred monument: a simple wayside cross made of two massive wooden beams (without a body or INRI inscription), which already shows the wear and tear of wind and weather.
