Cycling itinerary: Le Bourget du Lac to Yenne link

This link provides a two-way connection between Yenne and Lac du Bourget, passing from one side of the Montagne de l'épine to the other, without the need for difficult ascents, thanks to the dedicated gallery of the Tunnel du Chat.

This link between the two sides of the Montagne de l'Epine allows you to discover two different sides of the mountain via the tunnel du Chat. On the Yenne side, you'll travel through the landscapes of the Billième vineyards, on shared roads and a section of greenway.
On the Bourget-du-lac side, coming from Chambéry or Aix-les-Bains on the V63, you'll skirt the lake and its harbour, and enjoy the breathtaking panorama of Lac du Bourget. The climb up to Bourdeau is not very long, but has some steep gradients.
