I always use Viator to book our tours and skip the line tix before heading to Europe. Every purchase, tour or tix has been a smash! I'm writing on this trip to the Arc de Triomphe because it sums up how great these are. And this was just for the tix. We planned it for the day we landed day after Christmas knowing we'd be toast and not wanting to waste any time in Paris. We dropped our bags at the hotel and walked through the Tuileries Garden, crossed the Place de la Concorde and down the Champs-Élysées to the Arch de Triomphe. We followed the signs and went underground to cross the street to find the entrance where there was a long line of people waiting to get up. I just said keep walking...as we passed them all. At the front of the line we showed out tix and instantly were flagged in the first gate. Then to security. Again, flagged in for an instant check and in. We climbed those spiral stairs only to land on the benches up on top to rest! LOL Once we regrouped knowing we needed a nap before we tackled the rest of Paris, but we walked outside to the best views you can imagine all in about 10 minutes! Amazing. We are a big fan of Viator. Use them all the time.
Absolutely the most amazing view of Paris. The walk up is not nearly as bad as it may sound! If you can, try to get to the top a little before sunset and stay for a while and watch the sunset. Signs are clearly marked for access and knowledgeable drivers seem to know where to drop off in order to access the Arc de Triomphe.
