Beginning of this September we have 3 nights in Lyon prior to a river cruise. Would you take the train or would you drive? It would certainly only be a day trip. How are the roads en route? Dependable, or curvy and narrow(like some in the south of France)?
It's freeway but up and down over the mountains, twists and turns somewhat, but it's freeway, or rather mostly toll road.
okay...thank you...not sure if we wish to rent a car or take the train
I would take the train. I did drive there a few years ago, but if I was doing a day trip, I would take the train. Once you're in the city centre you don't want or need a car. You can explore the city on foot. So, why pay for parking and the stress of driving? On my trip I was headed on to Chamonix after a couple of days.
Personally, I'd take the train over renting a car (unless you're already planning on having a car while you're in Lyon). There's also a bus that takes about the same amount of time as the train. It's definitely worth the time to get there for a day trip, I loved Annecy - my favorite small city in France, so scenic.
