Seine River Tour

These guys a pretty good: http://vedettesdupontneuf.com

Do you mean one of the Seine cruise boats? They all do the same route, but I like Vedettes du Pont Neuf. There are also the Bateaux Mouches, and Bateaux Parisiens. Each has their own web site. Book in advance or just show up at the dock.

We sent at night to see the beautiful lights of Paris. Boarded at the pier just below
and across the street from the Eiffel Tower. We bought our tickets out of a machine,
boarded our boat about 20 minutes later. Sit on the upper deck and enjoy the night time Paris. Of course you will have to wait until dark and that is later during the summer.....but worth it.
Enjoy

Avoid Bateau Mouches -- it caters to the large tour groups. We learned this the hard way.

Hi eddy
From another point of view. We are 3 (60+ friends) and 1 (30 yo daughter), 2 have never been to paris, gonna treat them to a river cruise with champagne - bliss!!! booked with getyouguide.com. It cost more ($60) private salon and deck up front, 3 champagnes with sommelier and talks of monuments and champagne. We are surprising them with our adventure that they have no clue, an adventure of a lifetime with lots of memories. We are here to enjoy and not penny pinch here and there. Have a great time and c'est la vie
