Sadly, as most tourist pass through Lyon, on their way from/to Paris, this beautiful town does not get the credit it deserves... But maybe that is also part of its authenticity as it is not as crammed with tourists...
The old town, the roman ruins, the huge Basilica perched atop the hill, the lively center, the intriguing "traboules" (tunnels through the blocks linking the old streets through superb medieval courtyards) are enough to spend a couple of days in the town.
What's more, some districts like The slopes are full of nooks and crannies where you can discover some alternative places which are a lot of fun to hang out at (boardgame cafes, chicha places...) and to be remembered : Lyon is the capital of gastronomy. In my eyes, one of 5 stops that must not be missed in France...
Paris is beautiful but it is not France, more like a tourist living museum.
Lyon is much more representative of France.

Si vous voulez retrouver la magie d'une ville drapée de mille feux en plein coeur de l'hiver, ne manquez pas la «Fête des Lumières». Première semaine de décembre, Lyon attire chaque année des millions de visiteurs et des artistes du monde entier. La capitale des Gaules se transforme alors en véritable laboratoire de création.

Lyon, nice historical and modern city of France near the Alpes. Worth a one day or two day trip. Has been THE centre of textile trade you also see in architecture of the old town; Has a nice little tram system quit modern... you can leave the car outside the town. If weather is fine have a day trip in the alpes for skiing or walking.

Lyon is a wonderful city to live in.
If you go there for a visit go up to the Church at the top of Fourvière and admire a magnificient view (for those who don't feel like walking all the way a small train will take you to the top).
After going down, walk around the little streets of the vieux Lyon and check out some of the shops and pubs.
If you have children with you, I suggest going to the Tete d'Or parc and its zoo (free !), with its lions (if you're lucky they might even roar), giraffes, elephants, monkeys...

Lyon is a gorgeous walking city. Make sure you don't overlook it and take time to walk through its park and enjoy the fine restaurants the city offers.

Long time ago, since I was in Lyon...

When travelling to Lyon, you've got to go to the Place Bellecour which is the largest square in Europe! pretty amazing huh?! then you can take the streetcar to Fourvière, from which there's a really nice view of the whole city, all the more if the weather's clear.

Go for a walk in the old city. Its very nice there.

Hot in the summer make sure you have lots to drink if you are sightseeing.

great for news year eve
