Know which train station you want to stop at
The TGV will take you to the cool Lyon Part-Dieu train station ("gare"), a little far from what you want to visit in Lyon. Take the local train from there to Lyon Perrache if you arrive on the high-speed train.
TGV to Lyon
I took the TGV from Paris to Lyon and from Lyon back to Brussels, I paid 130€.
From Paris to Lyon it took me 2hours, but my seat was on the second floor and it bounces a lot, luckely I was very tired so I slept all the way.
Parc de la tete d'or
It is rumoured that a golden head of Jesus is buried within the grounds of Lyon's beautiful park, which is how it got its name. Who knows? The strict park-keepers will not let you go digging it up, they don't even like you picnicking on certain meadows. Nevertheless, this is a fabulous place to spend a sunny day, because there really is so much to see.
It reminded me at first of one of the big English parks in London, Regents Park in particular. There is a large boating lake, and acres of green fields. There is a huge botanical garden, full of species from around the world. Inside the large greenhouse you will see African rainforest trees side by side with Mexican cacti and Asian shrubs, but it is the large collection of carnivorous plants that attracted me. Loud frogs and baby ducks are everywhere in the ponds, and these lead you into the zoo.
Unlike so many zoos this one is free to the public, boasting a large collection of animals such as lions, giraffes, tigers, elephants, and hilarious monkeys. You may or may not agree with zoos - if you do not, then you might not enjoy it here - it is a typical menagerie, really, and the animals do not have enough room. On the other hand, there are children everywhere and this is the only way they can be educated about the wild animals of the world.
Such a great park with so much to do, I would definitely recommend it to anybody.
Roman Era Theatres
There are two Roman theatres on the Fourviere hillside, both of which were built on the site where Lugdunum was founded in 43 BC. The larger one is the oldest of its kind in France. The vestiges of a district which housed artisans can also be seen.
Between July and August there is a concert series held at le Grand Theatre, which has featured the likes of David Bowie, Jamiroquai, Oasis and Lenny Kravitz.
Bottom-line: Doesn't merit a trip in and of itself, but worth stopping by on your way down from visiting the Fouviere Basilica
Lyon was one of my favorite places in France, it is extremely romantic and beautiful. The cathedrals were stunning! There is so much history in that town including ancient ruins I believe. I would definatly recomend driving atop the hills to look down at the large busy city below and on your way down grap a cafe' americano with a french pastery and enjoy.
