Quick and knowledgeable

Hannah_R, Apr 2024

Our guide was very knowledgeable and provided us so much insight when looking at the fountain. We went to the fountain days prior and it was much more meaningful after spending time with our tour guide. The underground aqueduct was interesting and something different. Express tour was great after days of exploring Rome.

Overpriced

Jose_E, Mar 2024

Despite the knowledge and kindness of Jose, our guide, from who we learned a lot about the fountain and history in general, this activity feels really overpriced compare to other similar activities in the area.

Tour & Guide were amazing!

Tiffany_J, Feb 2024

Tour and guide were amazing - very imformative. There was time afterwards where our guide walked us over to a small, tucked away church which was an added bonus.

The fountain itself, details that often go unnoticed without the knowledge of a guide… also the barber cup story.

Interesting and informative

Gloria_B, Oct 2023

I was the only one on the tour. Paul was a great guide. Very knowledgeable about the history of the Trevi and the underground. He also had suggestions for local craft beer. Turned out he's from Colorado too. Small world.

Great history lesson

Lynne_B, Oct 2023

Great tour, wonderful to see the ruins and aqueduct, and to understand the build of the Trevi Fountain and what each section includes. Well worth it

Highly recommend

Linda_A, Sep 2023

Our guide was fabulous. He led us through the crowd and directly in front of the fountain were we threw our coins. He also had us drink from the Trevi fountain while taking our picture. The underground portion was short but very interesting. Highly recommend this tour.

Underground Trefi fountain tour

Trish_V, Jul 2023

Excellent tour of the underground near the Trefi fountain. Entire family including teenagers loved it!

Uncovering Rome!

Kara_H, Mar 2023

Samuele was an exceptional tour guide, who very patiently and thoroughly answered all of our questions, and naturally showed his passion for what he does as he unraveled the history in front of us, and gave us the opportunity to piece it together with him. We would never have known there was so much to the Trevi Fountain, and the history of the site prior to it being built as well as after! What a smart and fascinating guy and tour. We unfortunately had to leave at the end, before it was complete, to catch another tour, but would have loved to have spent as long as he could have given us to learn more! Thank you Samuele for an outstanding afternoon!

Loved it!

Kgomotso_S, Feb 2023

Awww! Man, where do I start? It was very well rounded and so informative! A wonderful human being and explains with such storytelling abilities!

History lover

Anna_D, Jan 2023

Learning the history of Rome. Seeing where Rome truly began was awesome. Stepping back into the 1st century was quite something.

A great tour very expensive for English

Thomas_R, Nov 2022

When you read the title of the tour you think you’re going to look at the inner working parts of Trevi fountain that’s not true. What you do visit is a Roman site underground that was found recently and converted into a museum it is very interesting and I noticed that they were sold out the day we went so they are very popular. The guide was wonderful she explained the underground and Everything you want to know about Trevi fountain
