Perfect in every way! - Lovely cruise with a small group in a private section of cruise boat. Knowledgable sommeliers who was pleasant and engaging and enjoyed discussing the varieties. Delightful samples of three very different champagne types but all equally pleasing. And the views on both banks of the Seine were quite enjoyable. A relaxing way to end a long day of walking thru a beautiful city.

Lovely evening cruise on the Seine while experiencing great Champagne - We had a lovely cruise on the Seine and sampled 3 champagnes. There was a Blanc de Blanc, Rose and a blend aged longer. The explanation about the process to make champagne and the tasting notes of each was good.

A wonderful experience - Fabulous way to see Paris!! We had a private area on a large boat and tasted several delicious champagnes. Our guide was entertaining and very knowledgeable. Highly recommend!

Loved it!!! - I went with my daughter. We both had a great time! Our host was informative and fun. We were in a separate room for the tastings and also could go out on a private deck. Would book it again if we ever get back to Paris.

Wonderful experience, exceeding all expectations! - This was an absolutely wonderful experience. I read a lot of reviews of this tour prior to booking, some mixed. People are entitled to their opinions, but I truly can't understand how anyone could have a lackluster experience on this tour. I felt that our experience exceeded every expectation. Yes - you are on a large sightseeing boat. This is made clear on the website that describe the tour. I have to say, this really did not matter one bit. If i had not seen the boat before boarding, I would have never known. We were in a completely private, walled off area at the front of the boat with our own indoor and outdoor space. We boarded through a separate line all our own and did not hear or see a single person who was not with our small group the entire duration of the tour. We enjoyed a private, small group experience as promised by O Chateau. We were fortunate to tour with Clement who was absolutely fantastic. He was so welcoming, kind, and knowledgeable and truly made the experience what it was. The champagne was amazing and his expertise made the tasting unique without ever being over-bearing. We had 3 full glasses of champage, each one excellent, and Clement generously topped us off along the way. The views from the Seine were to die for, Clement pointed out his favorite elements of the city (both widely known and personally revered) along the way which was a wonderful way to see the city through a resident's eyes. He graciously took pictures of us in front of the Eiffel tower. Overall, a tremendous experience at the right price. I would go back again and again and again.

The Viator instructions... - The Viator instructions of where to meet were very helpful. Alain, our sommelier and guide pointed out interesting landmarks while also telling us about the different champagnes. It was a relaxing way to see the city and the Seine!

Wonderful Seinne Cruise! - Great experience — from excellent customer support that was needed, to enjoyable and knowledgeable champagne sommelier to delicious tasting! Highly recommend!

Great fun! - Experience was great fun! Sommelier was friendly and knowledgeable and made everyone feel comfortable. Very generous servings of champagne! Tour gets more and more fun as you go, so make sure you get something to eat before the tour! ;)

Wonderful and relaxing... - Wonderful and relaxing tour to end our day. Beautiful boat ride with a knowledgeable sommelier and delicious champagne .

Simply a boat ride - This is simply a run on the river. There is no education or information provided. The champagne was good and the event was fun but I had hoped for a tour and this was not that.
