TUNNEL ABSEILING PLUS tour the underground

If you’re seeking an adventure that combines history, adrenaline, and a touch of mystery, the Tunnel Abseiling Plus tour in Rovinj might just be your perfect fit. This 2.5-hour experience guides you through a 550-meter-long underground WWII fortress, offering not only a peek into Croatia’s hidden past but also the chance to learn abseiling techniques in a unique setting. It’s a thoughtfully designed outing that appeals to thrill-seekers, history buffs, and those eager to step out of their comfort zone.

What really captures the imagination is the combination of underground exploration with a series of abseils, culminating in a challenge that tests your nerve in near-complete darkness. The fact that it’s suitable for beginners—thanks to professional instructors—makes it accessible for most travelers. The inclusion of a wine tasting at the end adds a pleasant, social touch to this adrenaline-fueled journey.

In-Depth Review of the Tunnel Abseiling Plus Tour

The Setting: An Unfinished WWII Fortress

The adventure begins at the underground San Giovanni fortress, a site that’s as fascinating as it is unusual. Built during wartime but never fully completed, it’s a true mix of natural caves and human engineering. The fortress remained hidden and forgotten until recent years, when it was rediscovered, cleaned, and prepared for visitors. The result is a mysterious, atmospheric space that feels like stepping into history, with its high vaulted ceilings and labyrinthine tunnels.

Travelers will appreciate how this space combines raw natural geology with the thick concrete walls of the fort, creating a unique environment for abseiling. The interior’s cool 14°C temperature offers a reprieve from the Croatian heat, but it also means packing warm layers—something the reviews highlight as essential.

The Tour Experience: From Walkthrough to Adrenaline

The tour begins with a guided walk through the underground corridors, during which an audio-visual presentation transports you back in time. This multimedia feature, involving projections and special effects, sets the tone and immerses you in the history of the fort, making the experience more meaningful and engaging.

After the walkthrough, it’s time for the fun part—abseiling. The tour offers two options: the standard Abseil or the more challenging Abseil Plus. Both involve descending a natural rock face with safety equipment provided, all overseen by professional, certified guides. The guides, such as Ela, are praised for their enthusiasm and patience—”a cheerful, kind guide who shared stories about Rijeka’s history” according to one reviewer.

The Abseiling: Technical & Trustworthy

Most you will find that the abseiling is well-supported. The equipment is certified and regularly checked, and instructors provide thorough guidance. For those new to abseiling, the initial descents help build confidence, with instructors offering backup and reassurance.

The Abseil Plus option takes things further by including a descent on a cascading, uneven rock inside the fort. This part is more demanding, with a greater emphasis on technique and control. It’s perfect for those looking to push themselves slightly, or for thrill-seekers wanting an extra challenge. Some participants even try a simultaneous abseil, which adds a fun, team element.

The Dark Challenge: A Test of Nerve

For the bravest, the highlight is the final challenge—turning off your head-torch and navigating your way out in pitch darkness. This test of trust in your guides and your own senses adds an element of adventure that many find exhilarating. The feeling of emerging from the darkness into the light becomes a memorable moment, emphasizing how far you’ve come from the initial nerves.

Post-Tour Relaxation: Wine & Conversation

Once back above ground, the experience wraps up with a relaxed social hour, complete with a glass of Croatian wine. Reviewers mention that this is a pleasant way to unwind, chat with guides and fellow travelers, and reflect on the day’s adventure. It’s a simple but effective way to make the experience feel complete.
