Exploring the Underground Fortress San Giovanni

The San Giovanni underground fortress becomes accessible after years of being hidden and forgotten. Recently rediscovered, it features high underground rooms made of concrete and natural rock formations, making each visit uniquely intriguing. The architecture is a combination of human effort and natural elements, with unfinished sections adding to its mysterious appeal.

During the tour, visitors are led through two levels of the fortress, with the opportunity to experience multiple abseiling descents. The first descent involves a vertical walk down a rock face, suitable for all beginners. The second highlight is a more demanding descent on uneven, slippery cascading rocks inside the fortress, designed for those who want an extra challenge. The support of professional instructors allows participants to pick their comfort level and gradually build confidence with each descent.

Abseiling in the Fortress: Techniques and Variations

Both the Abseil and Abseil Plus versions include initial training on technique and equipment, with demonstrations provided by guides. The easier descent involves walking down a vertical rock, which is manageable even for first-timers. The more difficult descent involves a vertical jump, suitable for those comfortable with heights but still beginner-friendly thanks to instructor support.

The Abseil Plus extends the experience by adding another abseil — this time on the cascading rock within the fortress. Because this section is uneven and slippery, it offers a more demanding challenge. Participants can try a simultaneous abseil in pairs, adding a fun twist to the activity.

A key feature of this tour is that no previous experience is required, and each participant can decide on the spot which descent feels most comfortable. The guides are certified professionals, ensuring safety at all times, and each person is equipped with certified abseiling gear.

Safety, Equipment, and Practical Tips

The tour emphasizes safety and support, with all equipment regularly checked according to valid standards. Since non-slip shoes are mandatory, visitors should bring hiking shoes or sturdy sneakers. The temperature in the underground environment stays steady at 14°C, so packing warmer clothes is recommended, especially if spending extended time in the fortress.

Participants are advised to avoid the tour if suffering from epilepsy or claustrophobia. The activity is conducted at your own risk, and the guides provide thorough instruction and backup during each descent. The tour can be booked privately for other dates and times upon request, with flexible scheduling.
