What you can see in a tour

FAQ guided tours

Tours are open to anyone aged 10 or over. However, you should be able to complete the brisk
4.5-kilometre hike across uneven terrain in what is only a partially lit rock tunnel.

Before the tour, you will be issued with safety equipment (a helmet, a torch, a fluorescent jacket and a tracking device) and also be given a safety briefing. You will do the tour in a group of up to 20 people and will be accompanied by two trained guides. Visitors are asked to watch a safety video in advance and to fill out a short questionnaire in this regard.

Sturdy footwear (hiking boots or sturdy trainers (sneakers)) is required in the tunnel. In some parts of the tunnel, there may be water coming from the ceiling, so we recommend wearing a waterproof jacket. The temperature in the tunnel will be between 15 and 20 degrees Celsius.

No food or drink will be available around the entrance to the BedrettoLab or during the tour through the tunnel, so please bring your own drinks and snacks.

No. Tickets for the guided tours must be purchased in advance. Group numbers are limited to 20 people for safety reasons.

Based on experience of previous events, our visitors are mainly German and Italian speakers. However, if it turns out that there is a lot of demand for tours in English or French, we will make changes to our tour offering in the future/on request in order to accommodate this.
