Last spring, I went on a hike to mountains near Lac du Bourget: Montagne de la Biolle and Mont de Corsuet, located at the southern tip of the Massif de la Chambotte in the Jura mountains. Here is the trail that I followed (download KML):
In the morning, I took a train from Annecy to Albens, the station closest to the trailhead. At first, I walked on paved roads, until I reached the forest and started on the ascent to the Belvédère de la Chambotte. At the belvédère (viewpoint), there was a lot of fog so the view was limited. I then continued on the ridge towards the Croix de Meyrieu, on the Mont de Corsuet. I had lunch there then went down the mountain towards Aix-les-Bains. I made a detour to the Grotte des Fées (Fairy Cavern) on the way: By then, the fog had lifted a little so the view from there was pretty good. After a while, I reached Aix and the Sierroz river, which flows into Lac du Bourget. I followed it until the lake and the Grand Port.
