Montmin, or you could order a taxi, but remember to make arrangements to be collected later. The walk takes roughly 6 hours 30 minutes. You'll also need a picnic and a map would be wise.
9 a.m. - Near the church of Montmin there is a sign on a lavoir (washing trough) pointing you to La Tournette. Follow it through the village and up a tarmac road, which becomes a rough track.
The route is marked with green splashes all the way and takes you through woodland, past a dry river bed, through a wide rocky gulley and along a col with spectacular views. On a clear day, you can see Mont Blanc.
There is also a wealth of wildlife. You are more likely to hear the squeal of marmots than to see them, but the bouquetin (ibex) are far bolder.
Wolves have also been reintroduced and the locals insist they won't hurt you, although shepherds have been complaining bitterly about lost sheep.
6 p.m. - Time to head back to Annecy, either by taxi or by bicycle.
If you opted for a taxi, you could have dinner and then take the night train.
If you're on your bike, you won't be able to return it to the hire shop until morning, forcing you to spend another night with the healthy lake-dwellers.
Annecy has a wealth of eateries in the medieval centre.
It also has the Centre Bonlieu arts complex, which hosts festivals and has matinee as well as evening performances for the rainy days when the great outdoors is less alluring.
