We stayed in a caravan at a campsite at Doussard, which is just beyond the south end of the lake, in 2009. Conveniently located to watch the TDF time trial, which passed about 200m from the campsite entrance. The day before we were watching on the Col de la Colombier. Two days before that we went on a recce to look for a good vantage point near the bottom of the climb and I cycled back to the caravan over the col. Great fun. Compared to sustrans cycle farcilities french cycle tracks are fantastic. This is the one down the west side of Lake Annecy, along an old railway alignment. and it carried on to Faverges. (It may have been extended since.) Note the roadsign showing the cycletrack has priority at the crossroads. When in the car avoid the D1508 down the west side of the lake, it had a near permanent traffic jam. As for bike transport I remove the wheels, seatpost and pedals and put it in a roofbox, which will also take a lot of other junk packed around the frame. This does not hammer the fuel comsumption like having the bike on a roof rack and is much more secure when parked en route. It also fit (just) under the barrier at an underground car park in Annecy, which is just as well as I'd forgotten about it!
