We had an intention to go there, but not at the time we ended up there.
It was an amazingly beautiful experience.
The place is huge, and very well built. There are not much staff, but you can find help or ask questions if you need to.
We came there and hour and a half before closing and it was raining as well, but we got the best out of the place anyways.
There's a huge collection of plants and they all have tags with their latin and French names on them.
Very highly recommend this amazing place.
No entrance fee.
