We really enjoyed the catacombs! It was a really different tourist attraction than anything else we experienced in Paris. The line is very, very long. I think we waited about an hour to get in, but that is just to keep it from getting too crowded. There are a lot of stairs down and quite a few stairs up, so if you have any mobility problems- this would be a problem. Also, on the day we entered they were only taking cash and could not give change. This was not revealed until the front of the line- yikes! The floor is very damp and somewhat muddy. I would wear appropriate shoes. It can also get hot and clammy inside due to the fact that you are underground. We found it very fascinating- the entire experience made me want to learn more about what really happens underground in the catacombs. I would also make sure to bring a French dictionary as there is a lot of beautiful poetry but it doesn’t have a translation. There is no flash photography. I do wish there was more context and history given on the tour, but this is something you will have to research on your own.
