Site naturel de la Grotte de la Luire

A timeless voyage filled with sensations and emotions into the heart of a geological phenomenon unlike any other in the world: the Luire cave offers a unique form of guided tour.

Guided tour lasting around an hour
Once you have made your candle, you will make your way into the bowels of the Luire by lamplight, following in the footsteps of its first explorers over a century ago. Your guide will then let you experience the same emotions as these first adventurers did by showing you the impressive mysteries of the Luire and the dangers of exploring it. He will then bring you back to the modern day with a son et lumière show and a slide show that will give you an idea of the sheer scale of the phenomenon.
Day trip to the cave network extending 250 m underground.
Visits supervised by a caving instructor (for the day), equipment supplied, basic training provided. For groups of 5-7 people. Good physical condition required. Please consult us.
Average temperature in the cave: 7°C; wear warm clothes; thermal jackets are provided free of charge for the guided tour by lamplight.
During the summer holidays, light refreshments are available (bruschettas) from 11:00 to 17:00 on the new shaded terrace.
