Since the loops are so similar, the most practical way to choose is by pier. Book the boat that leaves from wherever you will already be.
At the Eiffel Tower
Bateaux Parisiens boards at Port de la Bourdonnais, at the foot of the tower on the left bank, and Vedettes de Paris boards a few steps away at Port de Suffren. Either one pairs naturally with a tower visit (see our Eiffel Tower tickets guide). Choose Vedettes de Paris if you want the live guide:
At the Pont de l’Alma
Bateaux Mouches sails from Port de la Conférence on the right bank, a short walk from the Champs-Élysées and avenue Montaigne, and it sails late into the evening all year. In winter (November to March) boats leave every 45 minutes from 10:15am to 9:30pm, and every 30 minutes from 4pm; from April to October, every 30 minutes from 10am to 10pm. Its tickets are not tied to a time, which makes it the easy choice if your plans are loose.
On the Île de la Cité
Vedettes du Pont Neuf leaves from the Square du Vert-Galant, the green tip of the island below the Pont Neuf, daily from 10:30am. It is the most central pier, within an easy walk of Notre-Dame, the Louvre and Saint-Germain, and its cruise has a live guide.
Using the river as transport
Batobus is a hop-on hop-off river shuttle with nine stops: the Eiffel Tower, Invalides, the Musée d’Orsay, Saint-Germain-des-Prés, Notre-Dame, the Jardin des Plantes, the Hôtel de Ville, the Louvre and Place de la Concorde. It is useful on a sightseeing day, not as an evening cruise. Winter hours, from November 2, 2026 to March 31, 2027, are 10am to 5pm Monday to Thursday and 10am to 7pm Friday to Sunday. Bags larger than 16 liters are not allowed on board.
Off the classic loop
Paris Canal runs a one-way, two-and-a-half-hour route from the Seine up the Canal Saint-Martin, through its locks, with live commentary in French and English. It is the only route of its kind, but its reviews are the weakest in this comparison, and you make your own way back.
