Great experience! In order to get full value for the money you should read all the information presented inside. The history of the sewage system of Paris is presented very clearly and the amazing evolution of the Parisian sewage is told.
If you don't mind to read a little, this is really exceptional and recommended experience.

The main attraction for me was the hilarity of it being an actual sewer. We stayed nearby so I insisted that we go. My boyfriend was not much impressed. There is heaps of information but I only read small portions of it. The place does smell but you should kind of expect that for a sewer - it could smell a lot worse. For what it is I could rate it 4 stars but that might imply it is one of the great sites in Paris. Go if it intrigues you. Don't go if it doesn't.

Don't do this. You walk underground over an ACTUAL sewer. The place utterly stinks and reeks. Sure the information might be interesting, but most of it is in French and the smell is so bad you want to vomit. I can't believe they allow people to walk over long corridors with sewage below! Save your money and read the Wikipedia article while sitting next to the Seine.

If you're interested in civil engineering or just want to do something a little different, the Musée des égouts may the place for you. Here you can stroll under real sewer tunnels and see the evolution of the sewers and its maintenance systems through time.

It's a really nice way to cool off on a hot day. Keep in mind though that you are walking through real sewers so although you won't be walking knee deep in water, if you are a germaphobe, you may want to skip this attraction.

A different thing to do in Paris. You get to discover a part of a city that you don't usually think about but that is vital for our modern societies.

One of the more obscure museums I've been to. They cover the history of fresh water and waste water in Paris. Anyone with an interest in how cities are designed with enjoy this. An hour will comfortably cover everything and there's even a gift shop at the end! No waiting in lines and it is covered by the Paris museum pass. It does smell, but it is a working sewer..

Interesting place. Not many places have access to actual sewers. Very informative about the network in a city that apparently is notable in the field.

It’s a very unique museum that you see, smell (the sewage) and listen (to the flowing sewage) at the same time! It’s not a touristy spot but definitely is worth a go unless you can’t tolerate the smell (but it is just normal sewage so it’s not difficult for a 30-45 minute stay inside). Beware of the overhead pipes and drippings though! The entrance is a bit hard to locate.

A very interesting underground museum. It's a unique experience but I don't recommend it if putrid smells make you feel nauseous.

Worth the price of admission but I wouldn’t go way out of my way or wait in line more than 10 minutes or so to buy tickets. They stop selling tickets one hour prior to the stated closing time and the gift shop closes sometime before that. Overall it is well done with interesting displays and just enough odor to remind you that there is sewer water running under the grates below.

The most extaordinary museum I've ever seen. All your senses are used: you see, hear, smell, feel. When you're in Paris, you have to go there!

Brilliant off beaten track museum offering information on sewers system in Paris, some history background, an exceptional opportunity to visit the sewers (not an imitation, the actual ones!) And to learn about fresh water in Paris through centuries up until now. It took me an hour to visit whole museum (I've read about 60%of the info provided there and 70% of the brochure they give at the entrance). No queues. Not crowded.
