A bioclimatic catastrophe soon follows: the noxious gas spreads rapidly around the globe...
Only the power of antimatter can release the cosmic energy needed to annihilate the catastrophe!
You'll have to work together to find its chemical formula, buried since 1928 in the depths of the cave.
But be careful! The underground river reaches its lowest level only once a century, so you'll have just 80 minutes to get out of the cave!
You'll be in a group of no more than 10 people.
You'll be accompanied by an enthusiastic guide.
The service includes a private tour of the cave during the activity.
Duration approx. 1h30.
For children aged 5 and over (free for toddlers, but no strollers in the cave).
Bring sneakers and a pullover (temperature 15° all year round).
