The Paris Sewer Museum: where it is, when to go, and what you'll see

What you'll see

It's a working section of the real network, visited on walkways. You follow the history of the Paris sewers, their famous failures and a few vaulted galleries. Readers of Les Misérables will recognise what Victor Hugo described at length. Expect humidity and a noticeable smell: bearable, but real. Not a visit for evening clothes.

Hours and prices

The museum opens Tuesday to Sunday, 10am-5pm, last entry 4pm. It closes on Mondays, 1 May and 25 December. Guides we checked in 2026 list €9 full price, €7 for 18-25s and free entry under 18. The City's official site was down for maintenance when we checked, so please confirm the price before you go. It's included in the Paris Museum Pass.

Getting there from us

We're on avenue Duquesne, on the other side of the Champ de Mars. The museum is on the Seine, about 800 m from the Eiffel Tower towards the Pont de l'Alma, so it pairs well with a walk along the quays or the musée du quai Branly a few hundred metres away. By public transport, Alma-Marceau (line 9) is just across the river and RER C stops at Pont de l'Alma. Buses 42, 63, 80 and 92 also stop there.

Our advice

An hour is enough. It's a good rainy-day option, and children often enjoy it, all the more since they get in free.
