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), where the effects of wind and weather are already visible.
