What awaits you during this activity : Underground hike : Speleology Discovery

Experience Mont Blanc isn’t only about the high altitude adventures, how about visiting the unground of the Alps, an unusual experience: speleology. Discover what is hiding under our mountains.

Caving consists in discovering underground environments dug naturally by water. On the one hand, you will experience a sporty and physical activity where you will certainly have to crawl, walk in the water or sneak inside narrow walls to discover the treasures that the caves have to offer.

On the other hand, you will understand that speleology allows you to tackle more scientific subjects such as geology, the formation of cavities or even hydrogeology, i.e. the circulation of underground water. Such a wonderful opportunity to learn from a speleologist instructor all you need to know about the subject.

Equipped like real speleologists, you will discover a multitude of sensations in an exceptional underground world: beautiful galleries as the large rooms are called, underground rivers, stalactites, stalagmites and other incredible forms of the underground world...

The cave of the Prérouge (one of the largest underground networks in Savoy, which represents about 50 km with a difference in altitude of 860 meters), the Doria or the Bear, which still contains the vestiges of its prehistoric occupation. All these caves are located under the Bauges mountain range, in Savoie Mont Blanc.

Très bonne journée dans le creux de Cavale. Les explications de Matthieu nous ont aidé à comprendre cet univers extraordinaire et tout nouveau pour nous. Une sortie à notre rythme mais bien sportive, avec un vrai sentiment de sécurité. Tout à fait ce que nous recherchions. La prochaine fois, on tente le bivouac ! Merci Matthieu

Superbe expérience dans la grotte de Prérouge. La grotte est magnifique et le guide génial ! Il rend la sortie super intéressante, vivante et surtout il est à l'écoute et très pédagogue. Vous pouvez y aller les yeux fermés !
