The trip from Beynac to Chamonix proved to be more driving than we were prepared for. It's a vacation, after all, not a race. About 6pm we arrived in Annecy and decided to halt for the day. The TI was on the verge of closing and we knew if we didn't get a room soon, we'd be sleeping in the car. Since it was a FIAT Panda, neither of us was looking forward to that.
The TI in Annecy found us a room two towns away in Menthon-StBernard because everything in Annecy-proper was booked solid. When we finally saw the lake we understood why. Lac d'Annecy is a jewel. The water is as clear as spring water -- in fact, it might be spring water.
That evening we had fondue at a restaurant overlooking the lake as we watched the sun set behind the mountains across the water.
