The Seine: What Most Visitors Miss
The Seine runs 775 kilometres total, and the 13 kilometres through central Paris carry Notre-Dame, the Louvre, and the Musee d’Orsay along one continuous walk. Most visitors ride the Metro between these three and never notice they are all on the same riverbank stretch that UNESCO listed as a single World Heritage site in 1991, the full write-up of which lives on our Banks of the Seine page .

What the cruise shows that the walk does not
A cruise gets you the waterline angle on facades that photographs almost never use, worth doing once and ideally at dusk. It is not better than walking the quais, just a different view, and it is the one way to see both Notre-Dame and the Eiffel Tower moving past you at the same time without switching Metro lines. Search Seine cruises on Viator if you want to lock a specific time slot rather than queue at the dock.
Are the bouquinistes worth the time?
Yes, and most people walk past them entirely. The green book and print stalls bolted to the bridge parapets have operated on the Seine banks since the 16th century, in roughly their current form since the 19th, selling old maps, prints, and secondhand books for whatever the seller is asking that day. Browsing costs nothing unless something catches your eye.
Is Ile Saint-Louis worth a detour from Ile de la Cite?
Yes. It is the quieter of the two islands, residential, lined with 17th-century townhouses, and home to Berthillon, an ice cream shop described as the best in Paris often enough that the description has become accurate. Expect a queue; it moves fast enough to be worth it.
Paris Plages turns sections of the Right Bank expressway into sand and deckchairs every July and August, free to use. The rest of the year, the lower quais on both banks stay open to walkers and cyclists at every hour, which is the actual reason to see this stretch of river on foot at least once before boarding anything.
