TUNNEL ABSEILING PLUS tour the underground

Overview

2 hours 30 minutes

Mobile ticket

We descend the vertical natural rock and enter the high underground rooms built in concrete. We begin our walk through the fort accompanied by special audio-visual surprise that will take us back in time. Since the facility was built on two levels, there is another abseil for the participants of the Abseil Plus tour. At the end of the tour for the bravest, there is another challenge – turning off the head torches and finding the way out in pitch darkness.

At the exit we’re transported back to the starting point. We end the tours socializing and chatting with a glass of wine.

What To Expect

In this tour we visit the 550-meter-long underground World War II fortress and offer you the opportunity to try abseiling – descending a rock face with a rope. The fortress remained unfinished and is therefore a unique combination of architecture created by both man and nature. And that is not all. Until a few years ago, this building was forgotten and hidden. It was only recently discovered, put to rights and equipped for visitors. Depending on the difficulty level of the abseiling you want to try and you feel comfortable with, we offer this tour in 2 versions: Abseil and Abseil Plus. Abseil Plus In addition to the first two descents, there is also a descent on the cascading rock inside the fortress. Since that rock is a bit uneven and slippery, the descent is somewhat more demanding. Participants can prepare for this descent by executing the first abseils with the backup of an instructor. In this way, the feeling for the technique and sense of security are gradually acquired. On this tour, you can also try a simultaneous abseil in pairs.

Experience absolutely to do! Super recommended for those who want to try something different and adventurous. The guide (David) is really friendly and made us feel comfortable telling us the story of the tunnel and Rijeka. We really enjoyed the availability and sympathy of David. Consigliatissimo!!

What an amazing, unique experience. David was incredible. Brand new to anything like this, you go ‘through the ropes’ before hand and feel in safe hands the entire time. The tunnel system is impressive and they do a great job explaining the history. A sensory experience as well, especially when you turn off your headlamp in total darkness! DO THIS TOUR, you will not regret it.
Great adventure with some history thrown in. Excellent, patient guide

Did abseiling into the WW2 underground fortress tour. David was excellent and guided us safety through the tour. The first abseil is fairly straightforward, but we found the second a bit more challenging, but also more satisfying when completed. Would highly recommend and wish David and the company luck as they grow. Great value for money.
Gem of an Adventure!

Absolutely BRILLIANT!!! One of the best stimulation and adventure activities in all of Europe to truly understand the rich and complex history of the area. David and his group have invested hugely in creating the experience and their passion is visible in the quality of the tour. The detailing and caution to safety are super impressive. An absolute MUST DO!

We got lost finding the place. But reached out to the guide and he let us know where to go. It was a great experience for my family which includes two 14 year olds and an 11 year old. My youngest daughter was really nervous, but Lana and Marco went down beside her and talked her through each step. It was a great little adventure for us all.
Exciting experience

Marco and Lana were our amazing guides. It was my first time doing abseiling and they made me feel really comfortable. We could go at our own pace while also having a good laugh throughout. They were really informative and made sure we enjoyed our experience to the fullest! Would definitely recommend!
