From here, you can see the Lac de Sylans very well, the old ice houses located on its edge, and the view extends to the mountains of the Ain.

I wasn't sure at first because a mountain bike highlight said the road was closed. Fortunately, that's not the case, it's a very fast descent, even downhill in the tunnel. Some beautiful views of the valley.
