Underground Tour. From the Royal Palace to the Bourbon Gallery

Imagine walking through the hidden subterranean corridors of Naples, where centuries of history whisper from beneath your feet. For around $58 per person, you can join a 4-hour guided exploration that takes you from the bustling Piazza del Plebiscito to the mysterious underground passages connecting the Royal Palace to the Bourbon Gallery. Led by knowledgeable guides, this small-group experience promises personal attention and a genuine glimpse into Naples’ concealed past.

What we particularly love about this tour is how it combines stunning views of the city surface—from the Lungomare Caracciolo to Castel dell’Ovo—with the intriguing underground tunnels that reveal a different side of Naples’ civil engineering ingenuity. Plus, the chance to ride a raft across an underground canal adds a unique adventure twist that makes the experience truly memorable.

A potential consideration is that you’ll need to navigate a fair amount of walking and uneven surfaces, so comfortable shoes are a must. Also, the Bourbon Gallery ticket is not included in the tour price, so you’ll want to budget for that separately.

This experience suits travelers who enjoy authentic, off-the-beaten-path sights, history buffs who love underground stories, and those eager to get a well-rounded sense of Naples beyond its surface charm.

But beneath these lively surfaces lie mysterious tunnels and underground corridors that tell their own fascinating stories. This tour offers a rare opportunity to unlock those secrets, woven into a comprehensive exploration of the city’s underbelly.

The Perfect Balance of Surface and Subterranean Sights

The tour kicks off at Piazza del Gesù Nuovo, a bustling hub filled with history and activity. From here, you’ll stroll to the Lungomare Caracciolo, where stunning sea views and a lively vibe await.

This section alone offers a delightful mix of scenery, local life, and history—perfect for those wanting to soak in Naples’ coastal charm.

After the surface exploration, the focus shifts underground. The highlight is the Galleria Borbonica, a spectacular network of tunnels built in the 19th century. This civil engineering marvel was designed for military and civil use, connecting the Bourbon Palace to military barracks and other parts of the city. It’s a serene, slightly eerie journey beneath Naples, filled with narrow passages, stone arches, and historical artifacts.
