With its beautiful bridges, picturesque boat rides, and well-established history, this iconic river in Paris is more than just a pretty picture. It’s the lifeblood of the city.
But just how much do you really know about it?
We’ve compiled 10 Seine River facts that’ll give you a totally new perspective on the Paris river. Bonus: We’ll answer all your burning questions, such as “How deep is the Seine River?” or “Is Paris a water-surrounding city?” Let’s jump in (pun intended).
1. The Seine River is Long, Like Really Long
First of all, just how long is the Seine River? Measuring approximately 777 kilometers (483 miles) in length, the Seine meanders along the north rim of France before ultimately flowing into the English Channel. So, yes, it’s not merely hanging around in Paris. As a matter of fact, if you were wondering how close Paris is to the sea, the Seine has a little secret to tell you—Paris is roughly 210 km (130 miles) away from the sea.
The river winds its way through quaint towns such as Rouen and Hon fleur before it makes that salty entrance into the sea. Salt along the Seine? Yep, it’s where freshwater kisses saltwater in the estuary. Science-y, but adorbs.
2. It Flows Right Through the Heart of Paris
Still confused about which river flows through Paris? Yep, it’s the Seine. If you’ve Googled “what is the river in Paris” or “Paris river name,” this is your answer.
It divides the city into the Left Bank (Rive Gauche) and Right Bank (Rive Droite), giving us iconic neighborhoods like the Latin Quarter, Marais, and Saint-Germain-des-Press.
And no, Paris isn’t a water-surrounded city, but the Seine definitely makes it coastal-chic.
And here’s a little bonus for your Paris itinerary: Many of Paris’s most beautiful parks and gardens are just a stroll away from the riverbanks. Whether you’re craving a riverside picnic or a quiet morning walk surrounded by greenery, the city delivers.
3. The Seine River is Deep Enough to Cruise—But Not That Deep
So, how deep is the Seine River? On average, it’s about 9.5 meters (31 feet) deep in Paris. That’s deep enough for cargo barges, river cruises, and yes, those romantic Bateaux-Mooches you’ve seen all over Insta. But no, it’s not exactly “swim in it” deep unless you’re into risky business (or freezing temps).
4. The Seine River Has Its Own “Lake” Vibe
There is no tiny lake dead-center in the Seine, but some tranquil segments—particularly by islands such as Île de la Cite—have such peaceful energy that they may as well be lakes. Glassy surfaces, ripples as delicate as silk, morning fog—bleh, the look.
Plus, the Seine funnels into various canals and tributaries, making areas of water-pocket lakes hidden amidst the urban wasteland.
5. Pollution Has Been a Problem (But There’s Hope!)
Let’s discuss facts: Is Paris dirty? When it comes to the Seine, the answer was once a definite yes. For decades, Seine River pollution was a big problem—think garbage, sewage, and runoff aplenty.
But times are changing. The city’s been putting in overtime cleaning it up, particularly with the 2024 Paris Olympics, where swimming competitions were set to occur in the river. The authorities are also going all out to render the Seine swim-friendly once again by clearing pollution and enhancing biodiversity.
6. It’s Home to 37 Picture-Perfect Bridges
If you’re into architecture, this one’s for you. The Seine is lined with 37 bridges in Paris alone. From the ultra-historic Pont Neuf (ironically, the oldest bridge in town) to the Instagram able Pont Alexandre III, every crossing has a story.
