Entering the Underground World

The tour begins with a friendly introduction to abseiling techniques and familiarization with the equipment. Don’t worry — all gear is certified and regularly checked, and the guides are there to help you feel comfortable every step of the way. After a brief exercise on a horizontal surface, you’ll practice your descent, which is designed to be accessible for beginners. This initial step helps build confidence before facing the natural rock face.

Once geared up, you’ll step into the underground corridors of the fortress. The path takes you through high, concrete-walled chambers with special effects and lighting. This is where the experience becomes immersive, as the guided walk is accompanied by projections and audio-visual elements that recreate the atmosphere of wartime Croatia. It’s a clever way to blend history with adventure, making the whole experience more memorable.

The Abseiling Descent

The core of the tour involves descending a vertical natural rock — a manageable challenge for first-timers. The easier version involves walking down with a rope, a controlled descent that allows you to take in the surroundings safely. Participants can repeat this descent, or venture into the more difficult variant involving a vertical jump, which adds a thrill for those feeling more confident.

The ‘Abseil Plus’ version takes things a step further by including an additional descent on a cascading, uneven, and slightly slippery rock inside the fortress. This descent is more demanding but is executed with instructor backup, enabling participants to build technique and security gradually. For the brave, there’s also the chance to try a simultaneous abseil in pairs, adding a fun, team element to the adrenaline.

The Hidden Depths & Surprises

A highlight is the chance to turn off head torches and find your way out in pitch darkness — a playful challenge that tests your confidence and adds an element of excitement. After completing your descents, you’ll be transported back to the start in a comfortable air-conditioned van, with plenty of time to chat about the experience and relax with a glass of wine. The emphasis on safety and support from guides really shines here, ensuring you feel secure even if you’re new to such activities.

How the Tour Is Structured

The entire experience typically lasts several hours, with the underground exploration, the abseiling, and the post-tour socializing. The tour is available privately on request, with flexible scheduling, which means you can tailor the experience to your preferences. Pricing at $88 per person covers all equipment, entrance fees, an expert guide, and the audiovisual surprise, making it a solid value for an adventure that combines history, physical activity, and fun.
