Relive the first explorations by the flickering light of lanterns.

Immerse yourself for 1.5 hours in the silent darkness of the cave, just as you would have in 1780. Equipped with lanterns, you'll follow a 1,200-meter trail punctuated by shifting shadows and intimate lights. An unforgettable immersion that leads you to the monumental chamber of the Cathedral.

A unique sensory experience, suitable for ages 4 and up.
