Description by the author

Walk through the Grotte du Déroc and visit the Grotte du Louoi (Accessible between April 15th and November 1st)

Pay attention! This is not a standard walk! This walk includes a 350 meter long cave. You should not be afraid of crawling on your knees through a narrow passage.
You must also be agile. In particular, the descent after the visit to both caves is not a standard walking path but a steep rocky path where a tree is often a nice aid to support.

A rough sketch of the route through the Grotte du Déroc has been added under "Route information".

This walk can only be made between April 15 and November 1 due to the breeding season of the bats.
Do not go out during or after a rain shower. Also do not go out at a high water level. Don't forget a flashlight!
The passage through the Ibie is not accessible at high tide.
With children you have to pay extra attention during the descent.

A straight line is drawn in the route map between the entrance and the exit of the Grotte du Déroc. There is no GPS coverage here. The walk through the cave is flat and mainly straight forward.

You can park your car near the starting point. If you are staying at the campsites Le Vieux Vallon, Ardechois or Rives d'Arc, you can walk from the campsite to the Old Bridge over the Ibie river and use it as a starting point.
