Gouffre Poudrey is accessible to the public limestone cave in the French Jura at Étalans in Doubs in the region Bourgogne Franche-Comté . It was officially celebrated for the first time by Eugène Fournier on February 5, 1899 .

The cave is 70 m underground, the cave ceiling is 30 m thick. It has a circumference of 400 m and a maximum diameter of 130 m. This makes the hall one of the ten largest cavities in Europe and the fourth largest in France. The hard limestone layer of the Astartien made it possible that not a vault but a flat ceiling was formed.

A sinkhole that opened around 30,000 years ago allows easy access to the cave. The seepage water forms a small lake, the outflow of which is only accessible for a few meters to the cave explorer. The brook probably emerges 15 km away as the source of the Breme, a tributary of the Loue near Ornans . The high-quality drinking water was collected over a period of 30 years for a nearby restaurant until 1970.
