Exploring Rijeka’s Hidden WWII Underground Forts: An Honest Review of the Basic WW2 & Underground Discovering the Unknown Tour
If you’re looking to add a touch of adventure and history to your trip to Italy—specifically Lazio—this WWII underground tour in Rijeka offers a unique blend of education, exploration, and even a bit of relaxation. Although the tour is based in Croatia, it’s an experience that captures the imagination without breaking the bank at just $35 per person. We think it’s worth considering if you’re into military history, underground sites, or just want something offbeat from typical tourist paths.
What really caught our eye about this experience are two things. First, the access to a rarely seen part of Rijeka — the entrance of the unfinished underground fortress San Giovanni, which is usually closed to the public. Second, the use of special effects and projections, which promise to make the past come alive in a vividly immersive way. On the flip side, one thing to keep in mind is that the tour involves underground, enclosed spaces where temperature and lighting conditions are quite different from above ground, so comfort and safety are considerations.
This tour is ideal for history buffs, curious travelers eager for a mini-adventure, or those simply wanting to see a different side of Rijeka. It’s not particularly family-oriented, given the involvement of underground spaces and some restrictions, but it’s a great pick for adults who enjoy stories of battles, forts, and wartime secrets.

A Closer Look at the Tour Experience

Starting Point and Location
The tour begins at the entrance of the unfinished underground fortress San Giovanni, an area that’s normally off-limits to the general public. As you arrive, you’ll notice it’s a part of Rijeka that most travelers don’t get to see. The guides explain that the site served as a strategic military point, with battles and forts shaping the city over decades.
What’s Included and How It Feels
Included in the price are a guided tour, entrance to the underground fort, helmets and headlamps, special effects and projections, insurance, and a wine tasting at the end. This focus on safety and comfort makes the experience accessible, but you should still bring warm clothes since the underground temperature stays around 14°C (about 57°F). The use of headlamps and helmets adds to the sense of adventure and makes the exploration safer and more immersive.
The Journey Through History
Once inside, the guides do a good job of weaving stories about Rijeka’s wartime struggles, battles, and the strategic importance of these military sites. The use of special effects and projections is a fun way to visualize historical moments, especially if you’re a visual learner. Reviewers have remarked that this makes the experience memorable, with one noting, “The special effects really helped to bring the history alive, making it feel like you’re stepping back in time.”
Walking Through the Underground Maze
The tour isn’t overly long, but it’s packed with details about the fortress’s purpose and the battles fought there. It’s a mix of walking, observing, and listening, with some narrow corridors that might challenge those with claustrophobia, but overall, most visitors found it manageable. The group size tends to be small to maintain an intimate atmosphere, which is a plus for personal engagement.
Relaxing Finale with Wine
After the underground exploration, the tour winds down with a glass of wine, giving everyone a chance to chat, reflect, and soak up the atmosphere. It’s a nice touch that adds a relaxed vibe after the intensity of exploring wartime tunnels.
