French Guided tour

1h from Lyon, Genève or Annecy - In Jura's mountains

Duration: 1 hour (+30 min Belvedere)

Access the entrance to the underground.


A guide will explain the formation and history of the Caves of Cerdon in a simple and interactive way. You will walk between stalactites and stalagmites to emerge under a majestic porch which will allow you to choose:

  • to reach the reception of the site with the guide, or

  • continue through the siphon of the old river to reach a belvedere in the middle of the cliff overlooking the vineyard of Cerdon (return on your steps to the large porch).

This last section, which gives access to the belvedere, has a greater drop not recommended for people who do not wish to make an ascent effort.


To extend your day in the great outdoors, opt for the 1-day Pass (visit to the Caves and prehistorics workshops) and learn about the gestures and know-how of our prehistoric ancestors.

Questions sur les Grottes
  • Are there many stairs in the Caves?

      • The tour of the caves is divided into 2 parts (see the sectional plan):
      • Part 1: the 800-meter-long upper gallery corresponds to an elevation gain of approximately 5 floors to descend gradually. It has several stops to take advantage of the premises.
      • Part 2: The large room and the old siphon which leads to the belvedere overlooking the Cerdon’s valley and its vineyard.
      • This second section extends the visit circuit by around 400 meters with an additional elevation equivalent to approximately 5 floors. After a break on the belvedere to admire the Cerdon’s valley, the ascent takes place at your own rhythm to the reception.
    • I am accompanied by a person in a wheelchair, can I visit the caves ?
      • The entire reception area (ticket office, shop, snack point and toilets) is wheelchair accessible independently. The Caves of Cerdon cannot be visited in a wheelchair or with a stroller. The park is accessible with the help of a wheelchair attendant. The park's trails are mostly grassy..

    • What is the temperature in the cave ?
      • The upper gallery is at 13/14 °C and then drops to around 10 °C at the end of the large hall. For the second part, the temperature drops to 4 °C for 5 minutes. On the belvedere, you will find the outside temperature.


      • It is the temperature differences and the elevation that make this second part of the visit more physical.
