The lake Annecy cycleway is such a superb facility and when you see how busy it is with the range of people families and in line skaters using it daily it makes you realise what a choked up route the road along the lake would be if they were all in cars. It runs all the way into the hills and on to Albertville Ski village for a great flat explore. Shame it dosen’t do a full lap, but its great for going into the centre from the campsites.
Cycle way is a poor term, its like a proper cycle road and the surface is superb. 31km in total according to this map if you search on u-tube there are a few videos of the ride and there is a tunnel for added fun for the kids too.
There are other signed road routes too, some for the serious climber. Local routes
