I went to Paris Lounge Travel Agency for my Eiffel Tower Tour. The tour was great and the tour guide was very knowledgeable. We met at their office headquarters and from there we were divided up into 8 groups and a tour guide was assigned to each group. We all walked basically the same route to the Eiffel Tower. We were given a bit of history about the tower. We went through security and the second floor. Absolutely beautiful!! Some of us paid to go to the summit. After touring the second floor, we got back on the elevator and went up to the top floor of the Eiffel Tower. It was majestic and breathtaking. Now I must admit there are barriers there to prevent anyone from jumping from the top floor. You can still take beautiful pictures with unobstructed views. There is a concession stand where you can buy a glass of champagne. It's definitely worth it. I enjoyed the tour and our tour guide was very informative. I found this agency on Trip Advisor. read more
