NIGHT BIKE TOUR
(Reservations not needed for this tour to visit Paris—you will love this tour!)
Our Night Tour is the way to experience the “City of Light” at its best!
Ride through the Latin Quarter and witness the best nightlife in town. Pedal down the lle de la Cite, along the river and enjoy ice cream at Berthillon (Paris’s most famous ice cream shop). See the Louvre as never before (free concert often included) and relax onboard a boat trip on the Seine. Did we mention free wine is provided on the boat?
Make on mistake—this tour is 100% different form our Day Tour in both route and information. Over 65% of our customers take both tours and we hope you will too. Also, be sure to eat something before coming or the wine may give you an unexpected hit! (4.5 hours)
