Behind-the-Scenes Eiffel Tower Tour Including Champ de Mars’ Underground Bunker

Behind the Scenes Eiffel Tower Tour Including Champ de Mars' Underground Bunker

Meet your expert guide in front of the world-famous Eiffel Tower, located on the bustling Champ de Mars in Paris. As you gaze up at this incredible monument, your guide will get you up to speed about its history: hear how it was built for a world fair (the International Exposition of 1889), and learn how the locals’ opinions of it changed from ‘eyesore’ to ‘much-loved architectural icon.’

After your introduction, leave the tourist crowds behind and head underground to a little-known bunker, directly beneath the Champ de Mars. Explore the bunker with your guide, hearing wartime tales of this secret place that so few have seen. In its early days, the Eiffel Tower was used to house army communications equipment, and at the onset of World War I, the need for an easy evacuation route became apparent. The answer was the creation of the bunker, complete with secret tunnels, in a complex underground network beneath the tower.

Head back into the daylight and on to your next behind-the-scenes site – the Eiffel Tower engine room. Housing the machinery that powers the monument’s hugely important hydraulic elevators, the engine room represents the functional part of the tower’s day-to-day operations, as well as containing some beautiful infrastructure.

Take a ride in the hydraulic elevators to the 2nd level of the Eiffel Tower, home to Alain Ducasse’s prestigious Le Jules Verne restaurant. Michelin-starred, the restaurant is one of the few places in the world where top views and top food go hand in hand. Normally reserved for Eiffel Tower employees only, the restaurant’s private rooftop terrace boasts incredible panoramic views over Paris – and you’ll be one of the privileged few to see them!

Your tour finishes back on the 2nd-level balcony, where you can spend as much time as you want walking around independently, taking in breathtaking views of the city. Before leaving, your expert guide will point out where you can purchase tickets for the 3rd level, should you wish to experience the Eiffel Tower from the very top!

We were at the designated area before time however nobody turned up for quite a while. A lovely man turned up and took the tour as the original tour guide did not show. Apart from this start the tour was amazing. The guide was very knowledgeable and made the tour fun as well. My husband really enjoyed seeing the inner workings of the elevators. My only comment would be that going out on the roof of the restaurant was really no big deal, it would be better if there was a skip the line to the top of the tower instead of this.

Worth every penny! Learned so much about the Eiffel Tower on this tour. Seeing how the elevators work was phenomenal. Bypassing the long line was a huge bonus. We highly recommend this tour.

Our tour guide Juan was funny and informative. He was kind and knowledgeable and encouraged questions. We recommend this tour for anyone who would like to learn about the history of the Eiffel Tower away from the crowds.

Our tour guide Rita discussed a few important dates in French history and outlined the construction of the Eiffel Tower. We were given a tour of the underground bunker and later shown the machinery operating the hydraulic lifts.
The tour guide escorted the group to the lifts minimal waiting and upon reaching the second level, pointed out the significant landmarks in Paris. We were then left to explore the Eiffel Tower ourselves and to get to the third level if we chose.
Rita interacted well with the children and adults in the group. Highly recommended.

Viator NEVER fails to deliver!!! This was an excellent tour. We were taken to areas that the general public does not get to see. The tour guide was quite knowledgeable. She was also very friendly.

5 star rating: Highly Recommended September 2015

It was an excellent tour and my husband so enjoyed the underground tour of the machinery. Our tour guide, I believe her name was Louise, was excellent! She spoke great English and was extremely knowledgeable. The price was good. Thank you

Interesting Tour. Have been to the Eiffel Tower many times and never knew the bunker even existed.

5 star rating: Highly Recommended September 2015

An amazing tour with a fantastic guide. Bunker from a historical perspective very interesting. Also, being able to see the mechanical/electrical/hydraulic workings of the the Eiffel tower- something I never thought I would see. THen skip the line to the second level. Guide was with us every step of the way- so informative.
This tour is a sleeper but absolutely worth every cent!!
