The weather was so-so on the fourth day as well, but I rented a my bicycle and made a tour of the valley and passed by the Lac d'Herriéta. Not much of a lake, more a pool. When I was there, there was a sign that said that the lake was closed(?). I did not go down to the lake, because I got a feeling that it was a private area. The whole thing looks strange, the land on the left appears to be on a lower level than the "lake".
