Fondue Underground

An unusual activity underground!

We suggest you spend time in the bowels of the earth. At the end of the activity, enjoy a fondue under the earth with the feeling of being out of time.

Welcome under the earth! Forget all your prejudices, fears and phobias.

We will adapt the activity so that participants can have fun depending on their level.

We will equip you with helmets, headlamps and caving suits. You will venture with our guides in magical settings … After this visit, you will arrive in the central cave where you will enjoy a fondue to the rhythm of the accordion. An original evening full of adventure !!

Activity Overview

After a few minutes of walking in the woods, you will reach the entrance of the Grotto where we will take care to equip you and to divide you in subgroup according to the levels of each one.

Once equipped, you will walk for 30 to 60 minutes through the meanders and gut underground. You will alternate between small winding passages and galleries of all sizes to reach the central cave.

During this initiatory walk, our guides will try to share with you their passion about the history and formation of this magnificent cave, its concretions, stalactites and stalagmites.

Upon your arrival, you will be amazed by this great circus lit by candles and our minstrel (optional) humming songs of the past.

Still in an nice atmosphere, we will welcome you by sabering the champagne and offer you to taste the famous fondue underground!
