If you’re planning a trip to Naples and want to uncover some of its lesser-known treasures, this Underground Tour from the Royal Palace to the Bourbon Gallery could be a fantastic choice. It’s a chance to walk through historic tunnels, see iconic landmarks, and get a glimpse of the city’s underground engineering marvels—all in about four hours.
What really drew us in are two standout features: first, the small-group size that promises a more personal experience with a knowledgeable guide, and second, the unique opportunity to see underground tunnels and ride a raft across an underground canal. That kind of adventure doesn’t come around every day.
However, a key consideration is that the tour does not include tickets to the Bourbon Gallery or the Royal Palace, so you’ll need to budget extra for those. Also, since the itinerary involves a fair amount of walking and exploring underground, it’s best suited for those comfortable with physical activity and possibly uneven surfaces.
If you’re a history buff, a curious traveler wanting a deeper look beneath the city, or someone who loves a mix of city sights and underground adventures, this tour should fit the bill.

Starting Point: Piazza del Gesu Nuovo
Your adventure kicks off at Piazza del Gesu Nuovo, a lively square full of history and activity. It’s a natural meeting point, with the Basilica of San Francesco di Paola and the Royal Palace nearby. The tour begins with a monolingual guide, which means you’ll get in-depth insights in one language—perfect for those who prefer streamlined, clear explanations.
A visitor named Viaro_S described the guide as “very friendly and knowledgeable, with anecdotes and curiosities about Naples’ history,” which is a great sign that you’ll be in good hands.
Exploring the Streets: Lungomare Caracciolo

It’s the kind of walk that allows you to soak in Naples’ vibrant atmosphere, with plenty of restaurants and cafes where you can stop for a drink or a bite.
Expect about an hour and a half here—enough time to admire the scenery and maybe snap some photos of the sweeping bay. This part of the tour is free of charge, making it a nice, relaxed transition before heading underground.
The Underground Adventure: Galleria Borbonica
The highlight of the tour is definitely the visit to the Galleria Borbonica, a historic tunnel built during the Bourbon reign. This underground passage was a civil engineering feat at the time and now serves as a fascinating window into Naples’ past.
Here, you’ll explore the tunnels, which once connected the Bourbon Palace to military barracks. The tour includes a ride on a raft over an underground canal—a fun and slightly adventurous element that adds a memorable twist.
While the tour price doesn’t include the Bourbon Gallery ticket, the experience of walking through the tunnels and seeing the engineering work firsthand is well worth it. Travelers have shared how much they appreciated the “impressive civil engineering” and the chance to see a different side of Naples.

Since the tour includes a fair amount of walking and exploring underground passages, wear comfortable shoes and appropriate clothing. The itinerary is designed to be flexible, but weather conditions won’t affect the tour, as it’s mostly indoors or underground.
