Our tour guide was extremely knowledgeable, professional and friendly. She explained everything so everyone could understand and grasp the layers of history. I would highly recommend thus tour and she should be applauded for her ethics.

Elena was my guide today, which made all the difference. I can see how this tour could be easily accomplished by simply buying an audio guide and touring the cistern by yourself; however Elena’s knowledge was so deep and her enthusiasm for the subject so great, that I couldn’t help but enjoy myself. If the other guides are as good as she, then it’s worth purchasing the tour.

Fantastic guide

Bret_H, Jul 2026

You will not regret this tour!

Carrie_D, Jul 2026

Excellent tour! Erica was the best guide, so knowledgeable about the history of Rome, and she made it interesting as well. I could have listened to her all day! You will have earbuds to hear well. The space is not big, but there is so much to see. I can’t imagine not having a guide, you would have no idea what you are looking at. Also get tickets to go down to the front of the Trevi Fountain, and a voucher for gelato at the shop right in front of the fountain. This is my fourth time in Rome, and this tour is one of my favorites we’ve done. Also is not too long and you have to to explore the area on your own. Highly recommend!

Guided tour is the only way to do this museum

Jessica_V, Jun 2026

Our tour guide Erica was extremely knowledgeable and made the museum worth going to. There is no way we would have gotten as much out of it via the audio guide. If you want to visit the museum, book this guided tour.

Okay Tour but Wonderful Guide.

Mario_O, Jun 2026

While I thought there was more to the Trevi Underground, the guide was wonderful. Make sure you know that the Underground portion is about the length of a living room and dining room. However, the guide Naomi was superb.

Robert_G, May 2026

extremely interesting, incredible insight into the water workings, skip the line to get close to the fountain a plus.

History in every step!

Miranda_I, Apr 2026

Such a great experience, history in every step. Erica, our guide, was welcoming and so informative, brought history to life with her knowledge and passion for Rome. Her ability to highlight each era of Rome using the layers of the exposed underground cistern and how each era was built on to improve conditions, detailing the Roman recycling system, the aquaducts that feed the beautiful fountains and their use today. Simply mindblowing. A must do for anyone coming to Rome. Grazie Mille Erica!

Great tour!

Why not ?

Giuliana_V, May 2025

It would it be nice to be taken to the fountain and be explained about it, who is represented in there and other details. Our tour guide took us to the underground and give us a very good and detailed history about the ancient Romans then ice cream!

Personalized. Worth the time and money.

Steve_B, Oct 2024

The personalized stories that our guide told and explained made it much more interesting than if I did this unguided. She was slow and courteous as we walked around, waiting for all of us to catch up to her. Before and afterwards she gave me a few tips on dinner and future destinations. I’ll be thinking of her in a few days when I visit Florence.

A nice surprise.

Michael_R, Sep 2024

The tour was fascinating. As stunning as the fountain itself is, I found it really interesting to learn about a different aspect of it.

Disappointed

Christopher_F, Sep 2024

This was a short tour. The visuals were very limited. I thought it would be longer and I thought we would see more

Erika made it interesting

Jane_S, Aug 2024

Tour guide Erika was excellent. The underground experience lacked substance as it was restricted to a small area. Still very interesting and nice to finish with an end of tour gelato.

No show guide disappoints

William_C, Jun 2024

Very disappointed as we waited over 40 minutes from the scheduled start time because our tour guide did not show and a substitute had to be found. The substitute guide did an outstanding job but the disappointment of having a customer wait like this is really inexcusable
