Discover the Hidden Side of Rijeka

Leave the usual tourist routes behind and explore a side of Rijeka that most visitors never see.

Enter the city’s hidden underground world and explore the fascinating Katarina B fortress, with more than 1,000 metres of tunnels and passages beneath the city.

Walk through forgotten underground spaces, discover hidden fortifications and hear the stories behind the places that shaped Rijeka’s history.

But the adventure doesn’t stay underground. Along the way, you’ll also enjoy panoramic views of Rijeka and Kvarner Bay, creating a unique combination of exploration, history and spectacular scenery.

This is not a typical sightseeing tour. It’s an active experience that takes you off the beaten path and into places rarely accessible to visitors.

To finish, relax and raise a glass of wine while taking in the views.

Explore the tunnels. Discover the secrets. Experience the hidden side of Rijeka.
