Arc de triomphe has brilliant views - watch out for the grumpy jobsworth at the barrier who shouted at me for having only one ticket for me and my daughter despite her being under 18 so not needing a paid ticket (you’d think he should know as he has one job…) but apart from that it was great. The Seine cruise was ok but not that easy to find.

Going to the top of Arc de Triomphe was one of the highlights of our trip to Paris. Just so you know, it is about 15 floors to the top, walking up a winding staircase. It is a magnificent view at the top, and interesting to watch the cars navigate the giant roundabout surrounding the Arc. The river cruise was nice, but PACKED (with a lot of young students). If you're thinking it will be leisurely and/or romantic, think again! It is nice to see the Seine and to go around the Ile de la Cite. Finally, the Arc and the cruise are not close to one another. You'll need to walk, catch a bus, or catch a taxi in between. It's at least a 30 minute walk.

I read the reviews and was not totally convinced until Ingot there. You just have to get on the line where you start climbing the stairs no wait needed As soon as you get to the place go to the security area and you’re on your way On the Senna river it’s even better. Just step into the line since once they start at 10 am it’s a continuos process. I read about waiting 40 min etc. I just got there scan my Cel electronic ticket that I received 2 days before the activity and was on my way to the tour which by the way was not crowded at about 1230 pm got one of the best seats on the house so the whole two activity package was really a skip the line process
