Pretty little pass on the edge of Lac du Bourget with breathtaking views. Very few cars and some beautiful laces that make you want to go dancing. Please note that the start is 500m below the tunnel.

The ascent of Col du Chat on the east side offers a fantastic view of the lake below. Enjoy the view during the ascent because once at the top, the environment will be wooded. The pass culminates at 638 meters above sea level.
