On most maps it is called "Lac d’Ilay". The other name probably comes from the small island "Île de la Motte" which is located in the lake.

A beautiful asphalt road through the valley of Carstic formations and with views of several small waterfalls. There are turns, so you have to be careful, because there are a lot of cars, especially on weekends. Stay close to the side.
