The Experience: What’s Included and What to Expect

This tour offers a comprehensive look at Rijeka’s military history, combined with the natural beauty of its surroundings. Starting and ending in the city center, the journey begins with a drive along notable roads like Louisiana and Petroleum roads, which are historically significant routes. This sets a compelling scene right from the start, giving you context about the city’s wartime defenses.

The Itinerary: A Journey Through Time and Nature

As you move through the tour, you’ll stop at key historic locations such as Banska vrata and the bridge at Paac, which are more than just photo opportunities—they’re pieces of the puzzle of Rijeka’s past. The bird’s eye view of the city from these vantage points helps contextualize what you’re about to see underground and why these sites matter.

The highlight is definitely the walk through the 1,000-meter-long underground fortress Katarina B. This part is particularly evocative because you’re physically walking through a real military structure built in the 1930s. As one reviewer mentions, it’s a “fascinating” experience, with helmets and headlamps making you feel like a secret agent or historian uncovering hidden secrets.

The underground fortress is not just an exploration in darkness—it’s a journey through the battle for Rijeka’s liberation during WWII. The guide’s storytelling brings to life the story of the Battle of Rijeka, making history tangible rather than just dates and facts.

Above-ground Fortresses and Views

After emerging from the underground, you’ll visit several above-ground fortresses. These sites offer beautiful views of the Rjeina river canyon, old mills, and the surrounding landscape. The easy hiking trail makes it accessible, and the sights add a scenic dimension to the historical exploration.

The End of the Tour: A Cultural Finish

The final stop is the unfinished underground fortress San Giovanni—a fitting place to reflect on the history you’ve just experienced. Here, the tour wraps up with a relaxed social segment where you’ll enjoy a glass of local wine and a short film about Rijeka’s post-WWII restoration efforts. Multiple reviews highlight how much participants enjoyed this blend of history, scenery, and local culture.

What to Bring

Because the underground parts are a consistent 14°C, it’s wise to bring warmer clothes—a light jacket or layers work well. Adequate footwear is also recommended, especially if you’re planning on walking or hiking along the trails.

Accessibility and Suitability

While most travelers can participate, the tour is not recommended for those with epileptic seizures or claustrophobia, due to the underground tunnels. The tour involves walking through narrow, enclosed spaces, but the group size and safety gear help make it manageable.
